Modelling stressedly-deformed condition of the soil massif including elements of the multipurpose facility with multystoried underground part

In work the option of the multipurpose underground complex being part of the multystoried high-rise building is considered. The complex settles down in underground part of  the building and carries out a base role, replacing with itself the usual plates-but-pile base. Predesigns by a method of final elements taking into account staging of construction of an underground complex and the land high-rise building are executed. Sizes and a picture of distribution   of vertical displacements are received as a result of calculations.

Influence of changes in constructive elements of protective constructions on behavior of the soil massif near deep ditches

Complex settlement justification of construction projects, operation, reconstruction of constructions in difficult engineering-geological conditions, including in the constrained city building, became impossible without use of modern computer programs. In work the general approaches and results of modeling stressedly-deformed condition of the soil massif are considered at a postadiyny construction of a ditch for construction of one of hydraulic engineering constructions of St.-Petersburg under protection of a design «wall in soil».

Modeling of work of elements of the combined box-shaped and pile base in weak soil

In work results of modeling of work of two options of the multipurpose underground complex being the base of the multystoried high-rise building are considered. The complex plays a  role of the combined foundation. Modeling is executed taking into account stage-by-stage construction of underground and land part of the  building.

Numerical modeling of deep excavation structures behavior during construction

Numerical modeling of deep excavation construction is done in plane strain condition. The influence of boundary condition, contact condition between soil and structures, constrain of cantilever wall, thickness of the wall and anchors on the strain condition of the soil is found.

Mathematical modelling of geomechanical processes at the estimation of influence of building underground constructions in cities on the undermined rock mass

In work the basic features geomechanical processes of rocks occurring in a file are stated at tunneling and developments of underground constructions. Principles of the organisation mathematical modelling of processes displacement and deformations of rocks for an estimation of harmful influence of underground building on buildings and constructions are resulted. The basic lacks of known approaches to modelling of geomechanical processes are stated, recommendations about the decision of key problems of calculation displacement in a pedigree file are made. The basic results of application of the complex approach to a look-ahead estimation displacement and deformations at maintenance of building of city underground constructions in St.-Petersburg are presented.
