| 摘 要： | 为了解决节理化岩质边坡块体稳定性问题,利用3DEC在运动特征和变形分析方面的优势,探讨岩质边坡块体失稳动态过程,分析块体之间的相互关系,确定关键块体,然后利用块体理论评价其稳定性,为治理设计提供依据.实例应用表明:该方法可直观地模拟块体变形和运动特点,找出关键块体及其边界条件,正确地评价块体稳定性,也为边坡块体间稳定性相互影响问题的研究提供了一种新的更有效的方法,为制定合理的边坡支护措施及验证支护效果提供支撑.

| Abstract: | Block failure is a common failure mode of rock slopes with joints.In order to rationally evaluate the stability of rock slope blocks,the dynamic characteristics and reaction of blocks in rock mass failure are modeled using 3DEC method.The key block in rock slope can be identified by 3DEC simulation.Therefore,the stability of key block can be evaluated using block theory,which in turn provides useful input for slope design.A case study shows that it is an intuitional method to simulate blocks deformation and... |
