摘要: 降雨往往导致含裂隙土坡的失稳。在非饱和土广义固结理论的基础上,对某一边坡进行了变形与孔隙水、孔隙气流动的耦合分析。分析中考虑了非膨胀土和膨胀土边坡中不存在裂隙以及存在裂隙的情况,并对计算结果进行了对比分析。

Abstract: Landslides of stiff fissured clay often occurred during/after rainfall.Based on the generalized consolidation theory of unsaturated soils,coupled analysis of deformation of soil skeleton and movement of pore water and pore air in stiff fissured clay and swelling soil were performed for a selected slope.In the analysis,the effect of rainfall and existence of fissures was simulated,and the calculated results with and without consideration of existence of fissures in the slope were also compared.
