| 摘 要： | 浅变质岩风化层岩体破碎,其力学特性特殊,在有限元分析中能取得有效结果的计算模型也不易确定,由理论分析确定的该类岩质失稳边坡滑动面与实际情况存在一定的差异,结合现场测斜管监测,采用有限元分析方法,可对该浅变质岩失稳边坡的滑动面进行确定,再通过在滑动面上施加弹簧单元模拟滑坡的失稳过程,对得到的力学特征的分析得出该类边坡滑动模式主要是以蠕滑-拉裂为主. |

| Abstract: | The weathered layer of epimetamorphic rock is cracked and its mechanic property is unique.Calculation models for effective results are difficult to identify when using the finite element analytic method.The sliding surface of side slope of unstable epimetamorphic rock obtained from theoretical analysis is not agreed with the actual situation.Through the finite element analytic method,this paper took an analysis on the sliding mechanism of unstable side slope for an epimetamorphic rock at the basis of on-sit... |
