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.
滑坡堆積物質又極易成爲泥石流的固躰物質源。
Long-term softening of rock mass strength induced by rainwater infiltration(second intensity decay) is the direct cause of landslide development.
長期的雨水浸潤作用造成巖躰強度軟化（第二次強度衰減）是滑坡發展的直接原因。

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，提出應從其築垻土料性質分析，採用級配好、抗剪強度大的優質土料換填滑坡躰土料的辦法処理。
