Underground engineering construction in the city can not avoid bringing about perturbation on the surrounding rock and soil and then endanger the adjacent buildings’ safety. This paper fixes the data of the ground settlement and moving calculation parameters by doing a back analysis of monitoring data which comes from ground settlement caused by subsurface excavation and combing with other engineering experience. This paper predicts the ground settlement,horizontal moving,horizontal deformation and the distortion of incline and curvatural by using the probability integral method.With the numerical simulation,the paper obtains the displacement, axial strain and structural moment’s deformation law which caused by the frame structure’s settlement.The result will provide technical support for the disaster prevention and reduction of underground engineering.
