采动沉陷区路堤边坡挡土墙力学特性分析

his paper analyzes the rule of surface deformation and studies the influence of buildings caused by mining。On the basis of making accurate prediction to the surface deformation caused by mining ,rational numerical calculation models were established. Studied the variation of additional stress and basal additional stress of the buttressed retaining wall by the surface movement caused by underground mining of deformation. According to the results of internal forces of retaining wall, for the problem of inadequate bearing capacity, use cement mixing pile to reinforce foundation meeting the capacity requirements. The study provide the basis of slope shoring in mining area and views for the retaining wall designing.
