摘要

针对一种含贯通性顺倾结构面的岩质边坡

开展地震波场传播特性、动力演化规律和破坏机制研究。基于华丽高速公路金沙江大桥桥址边坡

实施了数值分析及振动台模型试验。通过地震波场数值模拟

明确了地震波场受贯通性结构面影响

在贯通性结构面和坡面之间反复叠加

加速度放大效应较均质边坡增大约1.8倍。振动台模型试验中不断增大地震输入烈度

加速度响应在烈度为Ⅷ度时发生突变

边坡由弹性响应阶段进入塑性阶段。在裂度为Ⅸ度时坡脚附近裂缝进一步扩展、贯通

直至发生整体滑动失稳

滑动面沿后缘陡倾结构面剪出、贯通性顺倾结构面滑动、下部坡脚附近剪出。强震后受扰动边坡若处在塑性阶段/不稳定阶段

在其他外力触发下有可能发生滑坡灾害。

Abstract

In this paper

propagation characteristics of seismic wave field

dynamic evolution and failure mechanism of a rock slope with connective structural surface were studied. Based on the engineering background of the bank slope of Jinsha River Bridge

FEM analysis and a shaking table test were designed and completed. According to the results of FEM analysis

the connective structural surface caused significant change of the earthquake wave field. After multiple superposition of seismic wave of slope surface and connective structural surface

the PGA of the slope was 1.8 times of the PGA of a homogeneous slope. With the increasing earthquake intensity in the shaking table tests

the first sudden change happened at grade Ⅷ intensity

and the slope changed from elasticity to plasticity. Expansion

penetration

and even overall sliding happened at the slope at grade Ⅸ intensity. Slide surface slipped along steep structural surface on trailing edge and shear outlet neighboring slope toe by shear and slides along penetrating weak structural surface. Therefore

slope may be at the status of plasticity after an intensive earthquake and it may lead to landslide with external forces.
