Underground construction in dense urban areas requires solving many problems, the most important of which is to prevent excessive additional deformations of the bases, which surround the area of the construction of buildings and structures.In order to prevent deviant strains different methods are used in engineering practice. In the recent years our country began to use a very popular abroad method of compensation grouting, which is currently one of the most effective methods of protecting the land-based facilities from the influence of underground facilities. This method has another important advantage, which allows using it rather for stabilizing yield of buildings and structures continuing for various reasons (geological, technological, etc.), or for lifting them if the settlement has exceeded the standard value.The method involves injection of a slowly hardening compensation grouting solution of a definite viscosity, which has a mineral base (suspension), into the foundation soil of the structure, the settlement of which should be controlled or compensated.

The present paper is concerned with the method, research objective and the results of numerical simulation of change of stress-strain behaviour of soil masses when constructing underground complex. In order to get consistent results of forecast, all major factors affecting the results of design studies have been taken into account, including spatial performance of soil mass, enclosure structure and an adjacent context area, phasing of construction, site investigation, initial stress-strain behaviour of soil mass and elasto-plastic strain of soils. The authors give assessment of influence of pit excavation and subsequent construction on a context adjacent area and construction of an underground railroad. Results of the studies show that the proposed construction of an underground complex on the Tverskaya Zastava square would not have a significant impact on the surrounding buildings and subway structures. The spreading of the subsidence crater around the excavating pit is projected by 30...80 m. The ground lift directly below the bottom of the excavation pit in the places of metro stations and transport tunnels will be about 0.1 cm.
