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

Article preview

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».

Article preview

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.
