Influence Analysis of Water Level Regulation on Dam Foundation Seepage of Rubber Dam

According to the influence of water level regulation on the dam foundation seepage of rubber dam,taking Hutuo River rubber dam for an example,finite element method is adopted to simulate three-dimensional seepage of the dam foundation.The isoperimetric hexahedron elements are applied to simulate space distribution of each stratum and horizontal blanket of dam area and the seepage field distribution of dam foundation under different working conditions.And then the influence of upstream and downstream water level distribution regulation,the unit-width discharge and the seepage slope on the foundation seepage field are analyzed.The results show that the dam foundation meets seepage control requirements when regulating upstream water level.
