中文摘要：
降雨入渗主要是通过改变岩体边坡非饱和区渗流场引发边坡发生滑坡的，而不同降雨强度下的入渗又是降雨入渗的特例。本文针对裂隙程度比较大的岩体，把边坡岩体等效成连续介质，借鉴降雨入渗的分析方法，建立了不同降雨强度下的入渗分析数学模型并编制了相应的有限元计算程序。最后，通过算例分析了不同降雨强度下入渗过程中暂态饱和区的形成、发展以及暂态水压力分布、变化。
英文摘要：
Rainfall infiltration induces rock slope to slip by mostly changing seepage flow field in unsaturated zone of slope, and infiltration under different rainfall degrees is special instance of rainfall infiltration. In the light of high density fractured rock mass, which can be equivalent to continuum, a mathematical model for the analysis on infiltration under different rainfall degrees is established and a relevant finite element program is worked out with the analysis method of rainfall infiltration used for reference. At last, the formation and development of transient saturated zone, and the distribution and variation of transient water pressure in the process of infiltration under different rainfall degrees are described by an example.
