摘　　要：介绍了所进行的层状结构岩质边坡动力稳定性试验。结果表明,在水平地震动加速度达到0.4g时,层状结构岩质边坡就会出现局部的层间错动现象,当水平地震加速度达到0.8g时,层间结合力较弱的边坡将发生大面积的表面滑动和崩塌。而在铅直地震力作用下,当地震加速度达到1.0g时,才会出现破坏现象。因而对层状结构岩质边坡来说,其水平地震力造成的危害是主要的。The vibration test of models for dynamic stability of rock slope with layered structures is introduced in this paper. The results show that the rock slope of layered structure will slip in some area when horizontal seismic acceleration is reached 0.4g and there will be surface slide and collapse on a large scale when seismic acceleration is (0.8g.) The model do not begin to fail until vertical seismic acceleration is up to 1.0g. So horizontal seismic acceleration causes main damage to the rock slope with layered structures.
