SATURATED/UNSATURATED, UNSTEADY SEEPAGE ANALYSIS OF ROCK FRACTURED NETWORKS DUE TO THE PERCOLATION OF RAINFALL
降雨过程裂隙网络饱和/非饱和、非恒定渗流分析

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.
