ANSYS软件在有垂直防渗墙的堤坝及地基渗流计算中的应用

Application of ANSYS in Seepage Flow Field Computation for the Dike with Vertical Anti-seepage Wall and the Foundation

鉴于渗流场与温度场微分控制方程的可比拟性,根据渗流场基本方程及定解条件,运用ANSYS软件中“生死”单元技术及网格自适应功能,对具有垂直防渗墙的堤坝及地基的复杂渗流场问题进行计算分析。计算结果表明,该方法可以有效地计算分析复杂边界、多种介质的渗流场。

According to analogy between the differential control equation for seepage field and temperature field, and to fundamental equation and condition of definitive solution of seepage field, the function of adaptive mesh and activate-kill element of ANSYS is applied to calculate the dike with anti-seepage wall and complex seepage field of foundation. The result indicates that it is an effective way to solve the problem of seepage flow field with complex boundary and multi-media.
