| 摘 要： | 由于断层和节理切割，边坡岩体一般具有非连续特性，降雨入渗是影响其稳定的重要因素之一。应用饱和与非饱和渗流理论建立了岩体边坡的非稳定饱和与非饱和渗流分析模型，并采用块体系统的非连续变形分析建立了降雨入渗非饱和渗流场影响的岩体边坡稳定分析和评价模型。作为应用实例，对某高速公路岩体边坡在降雨入渗条件下的非稳定饱和与非饱和渗流场及其对边坡稳定性的影响进行详细分析，并对边坡的稳定性进行评价。

| Abstract: | Because of the cutting of fault and joint, most of rocks in slope is discontinuous. And the rainfall penetration is some most important factors affecting the stability and deformation of rock slope. Based on the unstable saturated-unsaturated seepage theory, an unstable saturated-unsaturated seepage analysis model is set up for the rock slope, and by use of the discontinuous deformation analysis(DDA), a stability analysis model is established for rock slope considering the effect of unstable saturated-unsaturated seepage field under rainfall penetration. Taken as an example, the effect of unstable saturated-unsaturated seepage field under rainfall penetration is analyzed in detail for a rock slope of a highway road, and the factor of safety is estimated. |
