Settlement and Bearing Capacity of Long Piles of Finite Rigidity with Enlarged Base with Due Regard for Non-Linear Properties of Surrounding Ground

The article provides a formulation and analytical solution of the problem of interaction of a compressible long pile and surrounding nonlinear-deformable soils. It is shown that the force applied to the pile head is distributed between the side surface and the pile base unevenly, and that the share of the base is not more than one third of the total force. To improve this share it is proposed to find the optimal ratio between the length and diameter of the pile, and also to arrange the broadening at the pile base. Accounting non-linear deformation properties of soils around the pile, and the compressibility of the pile makes it possible to approach the solution of the set task. It is proposed, in the course of numerical integration of nonlinear differential equations obtained, to set the boundary conditions at the level of the pile base so that the stress does not exceed the initial critical load. To do this for this diameter of the pile or its base, define the initial critical load and the corresponding settlement, taking into account the depth of the pile.

Keywords: long piles, enlarged base, piles of finite rigidity, nonlinear properties of soils, initial critical load.

Ways of Improving Technological Solutions of Construction of Pile Foundations of Residential Buildings Under Conditions of Urban Development

Modern technologies of constructing pile foundations of residential buildings are considered. For construction site located in the high-density urban development, advantages of using the technology of pressing of factory made piles are shown. Main limitations of the technology in the course of pressing piles in sections with layers of dense rocks when the soil resistance exceeds the maximum force of pressing have been established. In such cases it is proposed to use the combined impact of static loads and torsion moments on the pile. Experimental data confirming the efficiency of this method according to the criterion of reducing the applied force of pressing are presented. Main disadvantage of this method is a destruction of the pile head caused by the long-term impact of torsion moments. To solve this problem, the author has developed the technological parameters and sequence of works ensuring the preservation of the pile shaft implemented when a vibrator is installed on its side surface.

Keywords: pile foundation, pile pressing, vibration-torsion moment.

Experience in Construction of a Multifunctional Residential Complex

The article describes an experience in construction of a multifunctional residential complex (MRC) in the course of erection of which significant deviations of values of settlements and tilts of the foundation from predicted values obtained with the use of the program complex for structures calculation have been revealed. As a result, there was a danger of exceeding the limit values of settlements and tilts of the foundation. To clarify the reasons, additional research and corrected calculations of the foundation with due regard for pre-consolidation, filtration consolidation and creep of clay soils, as well as the influence of the enclosing structure of the pit have been carried out. Results of multi-variant calculations and their comparison with monitoring data made it possible to indentify the cause of deviations of monitoring results from calculated values.

Keywords: foundation, multifunctional complex, high-rise building, model of soil, enclosing structure of pit, filtration consolidation, creep, mathematical simulation.

Soil-Structure Interaction Calculations for the High-Rise Building Taking into Account Non-Linearity of Structural Materials and Soils

Soil-structure interaction calculations are crucial for making design decisions on construction of a structure even of a usual building. Importance of SSI calculations considerably increases at design of unique structures while there is no practice of their construction in geotechnical conditions of a given area. Calculations of a high-rise building based on soils pose special interest as we face necessity to evaluate deformations of soils under unusually high loads with account of nonlinear properties of structural materials and soils.

Keywords: high-rise building, underground structure, soil-structure interaction, non-linear and reological properties.

Retractable Screw Anchors «Atlant»

Under conditions of dense urban development anchor systems have a significant drawback: output of the anchor outside the limit of the construction site. This is unacceptable in the case of subsequent construction of new excavations and trenchless laying of communication at adjoining areas. To solve the problem of cutting the tubular pull of the anchor «Atlant» in the area of coupling of the free length and the root, specialists of «InzhProektStroy» and «Ankernye Sistemy» have developed the technique of burning of walls of steel pipes with a high-temperature gas jet released during the combustion of fireworks (termites). The technical feasibility to cut anchor tie rods and extract them, if necessary, from the surrounding soil massive is proved.

Keywords: screw anchors «Atlant», anchor tie rod, underground construction, slurry wall, sheet-pile wall, termite mix.

Geotechnical Monitoring of a Residential House

During the construction of a residential house, differential settlements of the building foundation, surpassing normative values, were revealed; this became the reason to conduct geotechnical monitoring. The purpose of geotechnical monitoring is to develop recommendations for preventing the further development of non-uniform deformations of the building ground base. In the course of geotechnical monitoring the following works were conducted: visual survey of building constructions of the building; geodesic and instrumental monitoring of building deformations; additional engineering-geological surveys; execution of check calculations; analysis of geotechnical monitoring results, and development of recommendations for further safe construction and operation of the buildings. On the basis of the results of conducted geotechnical monitoring, technical recommendations for strengthening the ground base, which make it possible to stabilize non-uniform settlements of the building, have been developed.

Keywords: geotechnical monitoring, non-uniform settlements of foundation, visual survey, geodesic and instrumental monitoring, simulation, strengthening of foundation.

Results of the study of load redistribution in the system «strip foundation – injection piles» depending on its geometrical parameters (foundation base width, pile length etc.) are presented. The simulation was executed in the program PLAXIS 3D Foundation. Equations, which make it possible to calculate load proportions transmitted to the base ground by the strip shallow foundation and injection piles, when they operate together, have been obtained. The proposed method of assessment of joint operation of strip foundations and injection piles in clay soils increases the reliability of technical solutions aimed at strengthening of reconstructed buildings foundations.

Keywords: strip foundation, injection pile, redistributions of loads, strengthening of foundations, reconstruction of buildings.

Urban Development and Labor Performance

The issue of urban development process organization and planning influence on the labor performance has not been systematically analyzed In Russian and foreign practice. Labor performance is one of the basic indicators of characteristics variety to determine the economy status, particularly in the construction industry. This article analyses the interrelation of the urban development organization and planning and labor performance on an example of the actual urban development process organization - design, preparation, construction and settlement of residential houses, schools, preschool, as well as its influence on the labor performance growth reserves in Moscow construction complex. The cost-based approach was used to value labor performance, which is regarded as triple economic characteristics. The normative settled object value is counted as a targeted investment program in accordance with the structure confirmed in construction cost estimate summary. The actual value corresponds to the payments of state organization customer net the damage amount identified during the retreat of the actual organization of the urban planning regulations process. The purpose of this article is to show the direct influence of the urban development process organization and planning on labor performance. This research identifies reserves of labor performance growth in the nowadays-urban development and the construction policy of Moscow. This is valid due to evaluation approach of the labor performance as a socio-economical, but not technological variable. Main reserves of labor performance growth, according to this approach, are associated with the reduction of the postponed settlement terms, compliance with the regulatory procedures to ensure timely execution of all stages of the urban development process, the reduction of wasteful expenditure and losses of the municipal and contractors’ budgets.

Keywords: urban development processes modeling, integrated economical evaluation of the urban development processes efficiency, performance growth reserves, recommendations on economical analysis of urban development processes.

Techniques for Providing Comfort in Energy-Efficient Buildings in Hot Climate*

Results of the optimization of criteria influencing on the comfort under conditions of dry hot climate are presented. The contemporary experience in designing and construction of housing is considered; the complex approach in the course of the analysis of conditions for ensuring the comfortable habitation is used. Architectural-planning decisions organizing heat energy flows between the external and internal surfaces of a wall are proposed. For this purpose, the external heat insulation system, which makes it possible to protect wall materials against heating, is proposed. It is also proposed to include adaptation factors which make it possible to adapt to the climate, lifestyle, and local culture in the urban and architectural planning in countries with hot climate.

Keywords: comfort, energy-efficient buildings, heat insulation materials, polyurethane foam.
