问题 单项选择题 案例分析题

某电站近坝库区边坡(见图),由中厚层白云岩及薄层白云质泥岩、砂质页岩组成,坡角35°,岩层倾角10°,后缘发现有张裂隙。

该边坡有可能破坏的主要形式是()。

A.切层滑坡

B.顺层滑坡

C.均质滑坡

D.跨层滑坡

答案

参考答案:B

解析:顺层滑坡发生在非均质的成层岩体中,岩层沿层面发生滑动。切层滑坡滑坡面穿切岩土层面,发生在岩层产状较平缓和与坡面反倾向的非均质岩层中。均质滑坡是指发生在均质的、没有明显层理的岩体或土体中的滑坡。图中岩体由中厚层白云岩及薄层白云质泥岩、砂质页岩组成,为非均质的成层岩体,又因为其坡角35°,岩层倾角10°,岩层将沿层面发生滑动,即属于顺层滑坡。
