The volumetric model taking and performed mathematical modeling the process of construction of the pit under the enclosing wall of secant piles. The results of mathematical modeling on the horizontal displacements of the pit wall. Set out conditions for the construction of the pit and the main technological solutions.
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.
Performed mathematical modeling the process of construction of the pit under the enclosing wall of secant piles. The results of mathematical modeling on the horizontal displacements of the pit wall.
