降雨入渗非饱和渗流影响的岩体边坡稳定非连续变形分析
Stability analysis for rock slope under rainfall penetration based on discontinuous deformation analysis
降雨入渗是岩体边坡失稳的重要因素之一。应用饱和—非饱和渗流理论建立了岩体边坡的非稳定饱和—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复杂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，对某水库岩体边坡在降雨入渗条件下的非稳定饱和-非饱和渗流场及其对边坡稳定性的影响进行了详细分析。
Rainfall infiltration is some most important factors that affect the stability and deformation of rock slope. Based on the unstable saturated-unsaturated seepage theory, by case of the discontinuous deformation analysis (DDA), a model of stability analysis is established for rock slope considering the complex seepage field. By way of an example of a reservoir rock slope, the influencing mechanism on rock slope of unstable saturated-unsaturated seepage is discussed in detail, and the factor of safety is estimated.
