摘　　要：按照比拟法将ADINA软件中用于计算温度场的功能转换来计算边坡渗流问题;并按西北黄土地区降雨的可能情况设定了降雨条件,计算了边坡渗流过程中的入渗时间、入渗深度及最大流速,得到初步结论:降雨持时只是在一定范围内影响入渗深度;滑坡在时间上存在滞后效应.The seepage of slope is calculated with the ADINA software.The rainfall types which probably appear in Loess Area of china s northwest are considered.The time and depth of rainfall infiltration and the maximum flow speed are calculated respectively.The duration of rainfall can influence the depth of infiltration within a certain range and there is a lag-effect in the formation of landslides.

关 键 词：降雨 边坡 ADINA软件 渗流场 孔隙水压力
