Arrangement of the Underground Space when Reconstructing Administrative Building
The reconstruction of the former administrative building dating back to the early 19-th century in the central part of St. Petersburg into a modern hotel is considered. Before dismantling the building to be reconstructed, the monitoring of surrounding buildings was organized, and strengthening of their foundations was carried out by the method of injection strengthening of the foundation body with the use of cement mortar injection and pitching of 75 inclined anchor piles of 25 m length and 200 mm diameter according to the “Titan” technology. The foundation pit enclosure was made with the use of sheet piles “Arselor” AZ 37-700 of 13.5 m length, cast-in-situ bored piles of 410 mm diameter and 27 m length; additionally, along the walls of existing buildings jet-grouting piles were installed to a depth of not less than 2 m from the base of the existing foundations. For installing the pile foundation under the building’s frame, 162 cast-in-situ bored piles of 550 mm diameter and 27 m length produced according to the technology of “Bauer” Co. were used. The schemes of structural conceptions are presented.

Keywords: reconstruction, underground space, foundation strengthening, foundation pit enclosure, piles, settlement, monitoring.

Interaction of the Thick-Walled Soil Cylinder with the Sandy Kernel and the Grillage

This article outlines the formulation and task solution of axially symmetric problem in quantitative assessment of stress-strain state composite soil cylinder with sandy core under the influence of external load from slab foundation, analytical and numerical methods is based on elastic-plastic properties of soils. It is shown that the axial force on the composite cylinder is distributed between the sand pile-drain and the surrounding pre-packed soft soil in proportion to their stiffness and diameter ratio. It is noted that at a certain load in the sand pile, plastic deformations occur as a result of which the stresses are redistributed, and the total deformation of the composite cylinder develops nonlinearly. It is shown that depending on the adopted estimated model of soil in the sand pile at stresses close to the ultimate formation of various forms of destruction, including the barrel at different levels. It is emphasized that this phenomenon was observed for the first time and requires further research and theoretical basis.

Keywords: stressed-strained state, sand pile, bearing capacity of pile, pile settling.

The Use of Jet Grouting Technology When Arranging Underground Volume under Conditions of Weak Clay Soils

The experience in arrangement of an underground structure in the height-density development under the conditions of prevalence of water-saturated clay soils is expounded. The effectiveness of the original idea of arranging the deep excavation with the use of short sheet piles and “jet grouting” technology is substantiated by calculations and verified in practice. The essence of the proposed method consists in the arrangement of a “rigid contour” along the perimeter of the excavation which makes it possible to excavate the ground within the pit in an open way. The “rigid contour” itself is a part of the underground structure which is arranged in the first turn. For this purpose, trenches of 10-15 m width are digged under the protection of sheet pile screen, preventively executed fixed layer of soil below the subgrade according to the “jet grouting” technology and the system of strutted sheeting. This method ensures the safety of the surrounding development and is economically reasonable.

Keywords: underground structure, safety of surrounding development, geotechnical monitoring, weak clay soil.

Ensuring Geotechnical Safety of a Building under Construction

It is shown that the computer simulation of the geotechnical situation during the construction of an object makes it possible to consider various scenarios of its development, from completely negative up to favorable, and to determine required deformation characteristics of a base. The proposed method of arrangement of “geomassif” with the help of reinforcement of the base with rigid elements according to the geometric grid makes it possible to obtain, in practice, the necessary value of efficient deformation module. The considered method for ensuring the geotechnical safety of buildings and structures on soils with low deformation characteristics, propositions of designing, works execution, and their quality control are one of basic components of developed now technical regulations for the use of technique of jet grouting of soil.

Keywords: mechanical safety, geotechnical forecast, geomassif, jet grouting of soil.

Geotechnical Simulation of Effect of Deep Excavation When Reconstructing the Building

Reconstruction of the building, consisting in addition of an additional volume to it including the developed underground part, which is conducted under the conditions of existing historical development, can lead to additional deformations and in some cases even to the destruction of existing buildings. In this case it is necessary to provide for some structural and technological decisions at the stage of building-assembling works with the purpose to ensure the structural safety of existing buildings and buildings under reconstruction. The choice of concrete measures and assessment of their efficiency it is better to make with the help of numerical simulation of different stages of the construction with due regard for the geotechnical situation and with different boundary conditions. Results of the geotechnical simulation of arranging the deep excavation when reconstructing the building in the historical part of Perm are presented in this article.

Keywords: cluttered conditions of development, dangerous engineering-geological processes, deep excavation, slurry wall, numerical simulation.

Selection of a Granulometric Composition of Sand-Gravel Mixes for Sand Blankets and Embankments
Results of the experimental study of mechanical properties of sand soils with heterogeneous granulometric composition are presented. On the basis of definition of maximum density in the instrument of standard compaction and also definition of the general deformation module and internal friction angle in the instruments of compression and triaxial compression and the following statistical analysis, the nomograms for preliminary definition of mechanical properties according to the data on the granulometric composition have been developed. Findings reflect the basic regularities of formation of soils properties with heterogeneous granulometric composition and present recommendations for selecting the optimal granulometric composition of mixes for the construction of earthwork structures and artificial substructures. The recommendations presented make it possible to improve the rigidity and maximal density of such facilities without the use of special techniques of strengthening and additional costs.

Keywords: sand-gravel mixes, granulometric composition, maximal density, earthwork structures.

Foundation Underpinning of a Building under Construction with Jet Grouting Piles in Ryazansky Avenue in Moscow

In geotechnical construction, quite frequent are situations when during the construction and operation of buildings and structures the loads on the existing foundations change (increase). In this case a competent forecast of geotechnical situation development and adoption of measures for strengthening foundations are necessary. The experience of actions in such a situation is presented in this article. In connection with the change in functions of the building and in the number of storeys in it a complex of loads on the foundation structure has increased. Existing foundation slabs don’t ensure the required character of stress distribution on the earth foundation and normative value of difference in sediments, that’s way it is decided to strengthen the existing foundations with piles executed according to the technique of soil jet grouting.

Keywords: mechanical safety, geotechnical forecast, high load piles, jet grouting of soil.

Soil Consolidation with the Use of Jet Grouting for Reconstruction

Reconstruction of buildings, repairing and laying of sunken engineering networks in soft silty-clayey soils with a high groundwater level remains one of the tough problems of modern construction. The technology of arranging excavations and deep trenches under the conditions of high-density urban development gains an important role as a large number of objects have been built with above-limit deformations. It is shown that the problem is the reduction of values of additional settling when increasing loads in the course of adding storeys to old buildings, attaching new structures to old ones, laying and repairing underground communications, subway tunnel boring etc. It is concluded that testing cement-ground pillars with a statically pressing load on test sites is necessary before mass construction of structures with the use of jet grouting.

Keywords: jet grouting technology of soft clayey soils consolidation, test of soils with piles under pressing load, foundation strengthening.

About Amendments to Existing Legislation for Control the Quality of Design and Construction of Low-Rise Apartment Houses

The regulating effect of previously realized changes in the legislation for ensuring the construction safety, preventing accidents and protection of citizens against off-grade building products is assessed. It is revealed that the legislation-in-force makes no provision for control of quality of design and cost estimating documentation and also construction of low-rise apartment houses and objects of mass visiting with an area of up to 1500 m2 and the height of not more than 2 storeys which state and municipal customers buy at auctions before their construction and use for this the budget funds allocated according the program of resettlement of citizens from failing housing stock. The analysis of design and cost estimating documentation and results of inspections reveals shortcomings of design, construction and operation of low-rise apartment houses. Proposals for amendments to the legislation have been developed.

Keywords: low-rise house, construction, quality, expertise.
