摘要
Abstract
Elasto-plastic contact FEM with strength reduction method is employed to study the sensitivity of main influencing factors of coal measure strata shallow landslides. The calculation indicates that the sensitivity of shallow landslide stability of coal measure strata ranges from maximum to minimum as follows: the slope degree, the cohesion of slip surface soil, the internal friction angle of slip surface soil, the weathering depth, and the slope height. Elastic modulus and Poisson' s ratio of rock-soil mass have less impact on the stability of shallow landslide of coal measure strata. The research results provide theoretical reference for the design, construction and treatment of coal measure strata slopes.关键词
