| 摘 要： | 雨季岩质边坡失稳的主要原因之一是由于连续降雨在地下水位以上非饱和区形成暂态饱和区，使原来负的孔隙压力变成正的孔隙压力。降雨渗入岩体裂隙是饱和／非饱和、非恒定渗流过程。提出了这一过程的分析方法并给出一个岩石边坡工程降雨入渗分析的算例

| Abstract: | Slide of rock slopes in rain seasons is mainly due to temporarily saturated region above groundwater level changed from unsaturated region induced by rainfall, which is in accordance with the change of pore pressure from nagative to positive values. The percolation of rainfall into fracture networks is a saturated/unsaturaded, unsteady seepage process. A method of analysis for the process is proposed and an analysis of percolating of rainfall into a rock slope is given as an example in this paper. |
