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。
The finite element method is used to calculate the seepage field of sluice base. Considering the influence of drainage effect and sedimentation in the calculation process, the numerical solution of seepage field is obtained, and then the stability of floatation of hydrostatic tank can be calculated. Finally, Stability under the conditions of the safe use of water head. Through the numerical simulation of the seepage field of the sluice base, the curves of the stability coefficient of the sluice sluice pond with the upper and lower reaches of water level corresponding to different drainage effects are obtained under the conditions of siltation and non-siltation on the upstream and downstream. Provide guidance on the safe use of facilities.
