3-D FEM Analysis and Field Test for Effect of Slip Layer of Building Foundation in Mining Areas

Effects of slip layer of building foundation subjected to deformations of ground surface in mining areas were studied by 3-D FEM and field test, and results were compared. Bom showed under the condition of ground surface deformation,tension or compression, the presence of foundation slip layer reduces the additional stress effectively,and there is an upper limit for effect of horizontal deformation of ground surface to superstructure limit.
