直立岩质边坡的渐进性破坏模型试验研究
Experimental Study on Progressive Failure of Vertical Rock Slope
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, artificialmaterials are employed 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 destructi on process of vertical rock slope are obtained .
