地震作用下含弱面斜坡变形破坏实验研究
EXPERIMENTAL STUDY OF DEFORMATION AND FAILURE FOR SLOPES WITH WEAK PLANES UNDER EARTHQUAKE EFFECT
摘要
Abstract
Tnis paper examines the law of the deformation and failure of slopes associated with weak planes under earthquake effects. Experiments with a single three group weak surface slope model is carried out under simulated earthquake deformation and failure in shaking table. The digital speckle correlation method is used to process the experimental results. The displacement and strain of model slope are obtained. From the experimental results, it can be found that the displacement and strain are concentrated in the weak surface slope with the continuous vibration, eventually leading to the slope damage. It can be found from the experimental model comparisons that the deeper the weak surface in the slope body, the more stable the slope. The longer of the weak surface in the body, the less stable the slope. The test model first appeared fractures in the top, and then damaged along a weak surface , which is analyzed for the cause of the slope failure.关键词
