摘　　要：随着越来越多的高陡边坡的出现,碎裂岩质边坡的安全稳定性已经越来越引起人们的关注。以软弱破碎围岩为参照对象,利用模型试验对直立岩质边坡的渐进性破坏进行了研究。为此,首先利用人工材料实现对原型地层的模拟;随后,进行了模型试验方案的设计;最后,通过对试验结果的研究和分析,得出了直立岩质边坡破坏过程中位移以及岩体内部应力的变化规律。Along with the appearance of more and more high and steep slope, the safety and stability of rock slope has attracted increasingly attention recently. The fractured surrounding rock is taken as reference object, and a model test is carried out to study the progressive destruction of vertical rock slope. Firstly, artificial materials are em- ployed to simulate the prototype rock mass; secondly, the test programs and devices are designed; finally, by studying and analyzing the test results, the variation laws of displacement and internal rock stress during the destruction process of vertical rock slope are obtained.
