Abstract

Surface subsidence with various formation mechanisms possesses varied and complex influencing factors. Thus, studying surface subsidence mechanism and regularity under different special geological conditions is important in implementing disaster prevention and reduction programs. This paper focuses on goaf surface subsidence under the influence of the interaction between seism and fault, taking the Changping Expressway surface subsidence as the case study. In the full investigation of the engineering geological conditions in research area, the graphic method and numerical simulation method FLAC3D are adopted to study surface subsidence mechanism and regularity, after which the influence of seism and fault on surface subsidence is explored. The results show that the Changping Expressway surface subsidence is caused by earthquake-induced reactivation of the old goaf. Under the influence of geological fault, the maximum surface settlement significantly increased, the location of the maximum surface subsidence became close to the fault side, and the subsidence deformation showed an apparent discontinuity near the fault.
