地震效应和孔隙水压力对边坡稳定性影响的上限分析
Upper bound analysis of slopes under effect of pore -water and earthquake
摘要
Abstract
Based on the upper bound theory of limit analysis and strength reduction technique,the effects of pore-water and seismic forces on soil slopes were investigated.The failure surface was rotational and expressions are derived to calculate the safety of slope subjected to pore -water and earthquake loading.The upper bound solu-tions of those expressions are presented by applying iterative optimization method.Compared with the solutions from other analysis,it can be seen that the solutions presented here are effective.Parametric analysis shows that the safety factor of slopes decreases significantly with the increasing of pore -water and seismic forces.关键词
