Title: Bearing capacity calculation approach of composite subgrade in mining subsidence area
Abstract: Disturbed by underground mining,composite subgrade in mining subsidence area have large subsidence and horizontal displacement;however,normal beating capacity calculation approach neglects this influence.Based on the research on the subsidence influence on composite subgrade bearing capacity,an analysis model is established;and a bearing capacity calculation approach of composite subgrade considering the subsidence influence is presented.By an engineering case of ground improvement of a railway bridge in mining subsidence area,if the subsidence influence is considered,the bearing capacity of composite subgrade decreases somewhat.
