摘　　要：利用有限元Phase2软件,对带塑性混凝土心墙的坝体进行渗流分析,研究不同降雨条件下的坝坡渗流和稳定性影响。结果表明,降雨强度越大,坝坡安全系数越小;降雨量一定时,降雨强度越大,降雨时间越短,坝坡的安全系数越大;在降雨量一定时,降雨期间的峰值强度个数越多,坡体安全系数越大。Seepage analysis on dam slope with plastic concrete core wall is carried by limit element Phase2 software.Analysis on seepage and stability of dam slope is carried out under different rainfall conditions. The results show that the greater of the rainfall intensity, the smaller of the dam slope safety factor. When the rainfall is constant. The greater of the rainfall intensity and the shorter of the rainfall time, the greater of the dam slope safety factor. When the rainfall is constant. The more of the peak intensity is during the rainfall, the greater of the dam slope safety factor.
