Furthermore, as stresses in the stress field influence the value of seepage coefficient k, which will results in the change of seepage field in the end, while on the other hand, the seepage field also has an effect on the stress field because of seepage forces. Based on the coupling model of seepage field and stress field, a program by finite element method is developed in this paper. And the comparison of results of the program and criterion method with that of test shows that the test results are reasonable, which can be referred to analyze the causes of dangers, evaluate degree of safety of the body and foundation, and design and optimize the measures of seepage control.

此外，考虑到应力场中的应力会改变土体渗透系数进而影响渗流场、而渗流场也因其产生的渗透力会导致应力场发生变化，两者之间存在耦合作用，本文基于渗流场应力场耦合分析的数学模型编制了渗流计算有限元程序CCOSAS1.0，其计算结果和采用规范方法所获得的解答与实测值的对比分析表明，该规律合理且具有一定的代表性，可用以分析险情发生原因、评价堤身堤基安全状况及设计与优化渗流控制措施。
