Failure mechanism of slipping zone soil of the Qiangjiangping landslide in the Three Gorges reservoir area: A study based on Dead Load test

摘要

The Qiangjiangping landslide occurred during the rainy season after the first impoundment ofthe Three Gorges Reservoir up to 135 m. Rainfall and reservoir water are considered as two main inducementsfor its failure. The failure mechanism of the Qiangjiangping landslide induced by these two factors was exploredthrough Dead Load test (DL test). In the test,consolidation pressures σ1 and σ3 were kept unaltered to simulatethe deformation behavior and strength characteristics of the landside slipping zone soil while the matrix suctiondecreasing.
