Study and Application of Settlement Resistance and Correction Method of a Residential Building

Abstract

This subgrade is a large number of backfill soil and gravel pile foundation. The building produce settlement because of bearing capacity of foundation soil is poor. The rapid settlement of the building has been stopped using grouting techniques but the effect may not be quick; For the purpose of settlement resistance and deviation rectification, it is better to use a comprehensive treatment methods which combine the hollow grouting anchor static pressure pile, heaping load and drawing out soil with watering. It acquire a good effect of settlement resistance and deviation rectification. By establishing finite element model of the frame structure of the building using software of ANSYS, the housing stress and deformation in the process of rectification can be simulated and compare with the data of field. It can confrim a dependable construction schedule and insure the housing stress and deformation is in the range of safety.
