Geomechanical analysis of surface settlement trough development due to construction of deep underground pillar station

Geomechanical analysis of surface subsidence development due to construction of deep underground station is presented. The station is a typical pylon structure, which is usually used during construction of the latest subway station in Saint Petersburg. Numerical modeling of step-by-step underground station construction is conducted. The results of the numerical analysis allow to predict the magnitude of surface settlement and understand the wide of settlement trough.

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.

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.

The designing of the constructions of the pillar underground station with applying of the low-settle building technology

The intelligent technology of designing of the constructions of pillar  underground  station is adduced. Station is building with applying of low-settle technology, which takes into consideration main stages of the building process. The scheme of interaction of the system «support lining-soil massif» was accepted as basic scheme of calculations. The calculations of the stress-strain condition of constructions was performed with applying of finite-elements method.

Implementation of various failure criteria for numerical models of rock mass

The paper presents results of numerical modeling by application of plastic constitutive models with various failure criteria. The Balmer’s and Balandin’s failure criteria have been elaborated in FISH language and they have been applied to simulate two basic problems which are: compression of rock sample and construction of excavation in rock mass.
