Abstract: Disturbed by underground mining, composite subgrade in mining subsidence area have large subsidence and horizontal displacement; however, normal bearing 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.

Key words: composite subgrade, bearing capacity, surface subsidence
