摘　　要：应用有限元法对闸基渗流场进行计算,在计算过程中考虑排水效果和泥沙淤积的影响,得出渗流场的数值解,进而计算静水池的浮托稳定性,最后可确定静水池浮托稳定条件下的安全运用水头。通过对闸基渗流场的有限元法数值模拟,得到了上下游有淤积和无淤积情况下,对应于不同排水效果,拦河闸静水池稳定系数随上下游水位差的变化曲线,为该水利设施的安全运用提供指导。This paper deals with the application of finite element method in the study of seepage field of sluice foundation. The influences of the efficiency of bleeder well and the deposition of sediment are taken into account in the study. The numerical solution of seepage field is found by way of finite element method. Then, the uplift stability of stilling poll is figured up. Finally, the safety working head in the stilling pool under the uplift stabilility.
