Assessment of interaction the new construction object at full load and the surrounding building in the dense urban development conditions

The work is devoted to research the impact of a new building at full load after completion its construction has been investigated through an assessment interaction with envelope, ground mass base and foundation existing five-story building, in comparison deep excavation process engineering preparation for this construction, based on developed methodology studying objects nearby buildings complex geological conditions dense development conditions.
 For numerical studies stability combined space, proposed used, which built initial relations variational equations equilibrium equation surface six-dimensional stress theory limit state soil half-space introduction extended yield criterion plane problem nonlinear elasticity plasticity, provides determination value second critical load, solid sections ultimate appear half-space.
 From analysis movements nodes located vertical face «wall soil» structure (retaining wall pit), it can be concluded that transverse displacements retaining compared calculations according first option have changed opposite, associated formation sliding prism under passive pressure from side pile building. This indicates change stress-deformation influence during process, was evaluated version calculations, end analyzed calculations. In way, main urban determined, determining adjacent area condition bases foundations buildings, their preservation ensuring safe operation.
