地震过程中斜坡滑动破坏实验分析

Exprimental analysis of slope sliding failure during earthquake

为了研究地震引起的斜坡滑动破坏规律及其位移、应变的变化规律,利用数字散斑相关方法(DSCM),对主要受水平方向地震动荷载作用下的斜坡进行了实验模拟。结果表明,斜坡的破坏首先从模型底部弱面位置开始,沿弱面逐渐扩展,最终破坏;斜坡所含弱面的深度,对破坏过程有重要的影响。

In order to study the earthquake causing failure law of slope sliding and the change law of displacement and strain,using digital speckle correlation method（DSCM）,to the slope mainly by the horizontal dinly by the horizontal direction of the shock load do the experimental simulation.The results show that,the damagment of the slope fitst start from the bottom of model weak plane,then extend gradually along the weak plane and collapse at last,the depth of slipe weak plane have important influence to the failure law.
