地震作用下高边坡破坏的振动台试验
Shaking table test for high slope destruction under earthquake action
摘要
Abstract
Based on the shaking table model test,this paper discusses characteristic and failure mechanism of high slope of structures with weak interlayer surface and different slope forms.The influence of geological condi-tions and seismic loads on the failure deformation of the slop is also investigated.The experimental results show that the location of mud soft interlayer is easy to occur slip failure.The damage of convex slope mainly includes the collapse of slope shoulder and the integral slippage of the block above the variable slope line.Corresponding failure mechanism mainly is the top of the slope shoulder slipping off slope body.While the damage of convex slope mainly includes the collapse along the variable slope line and relative failure mechanism mainly is the vari-able slope line on tensile fissure driving the interface model of variable line cut-off collapse.The stability of con-vex slope is better than concave slope.The greater intensity of vibration results in more significant slope failure. The slope failure is more severe when the frequency is more close to that of the slope model.The duration is closely related with total energy of earthquake input.关键词
