| 摘 要： | 以鹰厦铁路K290滑坡为原型,基于降雨入渗情况下滑坡体呈饱和-非饱和渗流状态下,通过计算得到坡体孔隙水压力和体积含水量随降雨及地下水位变化的基本规律,进一步导入SIGMA/W程序并依据坡体孔隙水压力和体积含水量及地下水位变化特征分析了滑坡应力场,探讨了降雨强度、降雨持时和水位变化对滑坡体稳定性的影响.

| Abstract: | Based on the unsaturated and saturated slip soil with rainfall infiltration,the shear strength of unsaturated slip soil of K290 landslide along the Yingxia railway is analyzed.Then,the basic regularities of pore water stress,volume water content and ground water table are calculated.Furthermore,considering the various water tables,the influence on the parameters of shear strength and the contribution of suction,using SIGMA/W software,the stress field of landslide with the various rain intensity,raining time and the table of water are discussed,which lays a better guide for the analysis on the stability of unsaturated slope. |
