摘要
通过两个模型实验结果与计算结果的对照,验证了离散元法用于边坡分析的可行性,揭示了边坡破坏的机制,指出块体边坡内的应力分布是不连续的,并发现块体组合边坡内应力核存在的现象。
Comparing the measured results of two modelling experiments with thoseof numerical modelling by use of the discrete element method, the feasibilityof applying the discrete element method to slope failure is verified. The resultsreveal the mechanism of slope failure and show the discontinuity of stressdistribution in blocky slope, and we find out a phenomenon that there existsome 'stress nuclei' in the blocky slope when using the discrete elementmethod.
