摘　　要：为了分析降雨对毕机沟排土场渗流场的影响,采用筛分法得到排土场散体岩土块度分布规律,再利用Geo-Slope软件中的Van Genuchten模块建立排土场渗流数值模型,模拟出毕机沟排土场A-A、B-B、C-C三个剖面在正常工况、降雨1、3、7及15天后排土场边坡基质吸力分布及浸润线变化情况,分析其内部渗流场,得出该排土场边坡一般在降雨结束约(1~3) d后,坡内暂态饱和区基本消失,地下水位线局部区域有所抬高,而降雨15 d后地下水位基本恢复至降雨前的水平。The sieving method was adopted to get the distribution law of bulk rock and soil mass of the earth-disposing site,and then the Van Genuchten module in Geo-Slope software was adopted to establish a numerical model of earth-disposing site seepage,it is simulated slope matrix suction distribution and saturation line change situation with normal operating conditions of A-A,B-B,C-C profile of Bijigou earth-disposing site,and after rainfall for 1,3,7 and 15 days,its internal seepage field was analyzed,then it is got the following results,normally,the transient saturation zone basically disappears at earth-disposing site slope after rainfall finished for(1~3)days,a partial area of groundwater level was elevated in a certain degree,the groundwater level was basically returned to pre-rainfall levels after rainfall finished for 15 days.
