landslide-mass

基本解释

In the other sides, the deposition mass of landslide is apt to be the soild material source of debris-flow.
滑坡堆积物质又极易成为泥石流的固体物质源。
Long-term softening of rock mass strength induced by rainwater infiltration(second intensity decay) is the direct cause of landslide development.
长期的雨水浸润作用造成岩体强度软化（第二次强度衰减）是滑坡发展的直接原因。

Therefore, the quality of dam material should be firstly analyzed, and the best alternative method is to replace the landslide mass with well-graded and high shear-strength earth materials.
因而，提出应从其筑坝土料性质分析，采用级配好、抗剪强度大的优质土料换填滑坡体土料的办法处理。
