摘要:By analyzing the interaction mechanism of foundation-foundation-superstructure and considering the constraint effect of building structural stiffness on the stratum, the equivalent subsidence principle is used to propose the ground settlement prediction formula which considering the structural rigidity of the building to the stratum constraints, and verified its correctness through indoor model test. The results show that: 1) the structural stiffness has obvious restraining effect on the soil layer, so that the settlement curve caused by tunnel excavation tends to be uniform; 2) the greater the structural rigidity of the building, the more obvious the constraint on the soil layer, the surface settlement tank The wider and shallower; 3) The settlement prediction curve is close to the measured curve, and has good engineering applicability and practicability.
