基于Fluent的具有防渗墙堤基的渗流场数值模拟分析

摘要

为实现具有防渗墙防渗措施的河道堤防二维渗流场真实区域的数值模拟,采用有限体积法的Fluent数值模拟软件,利用其多孔介质模型,求解堤防基础的渗流场,并对采取防渗墙的单一防渗措施条件下的渗流场进行分析,结果表明,随着防渗墙深度的增加,其对河道堤防防渗效果明显但不是无限制的,由此可为堤防渗流计算及工程所需的合理的防渗墙深度提供依据.%The seepage stability is one of the key problems of embankment engineering.To realize the numerical simulation of real two-dimensional seepage field in river levee with diaphragm wall,the finite volume Fluent numerical simulation software and porous medium model were adopted to solve the seepage field of levee foundation,and then to anlyze the seepage field under the condition of single diaphragm wall seepage control measures.The results show that with the increase of the depth of the diaphragm wall,the seepage control effect on the river levee is obvious but not unlimited,which could be a basis for levee seepage calculation and the depth of reasonable waterproof wall needed by engineering.
