摘　　要：诸多实际工程中经常要求考虑渗流孔隙水压力对结构稳定性的影响,即渗流与结构的耦合计算问题。尝试利用ANSYS软件采用"生死单元"技术及网格自适应功能进行三维渗流场计算,采用邓肯-张原理建立应力计算数学模型,运用初始应力法进行三维应力场与渗流场的间接耦合计算。计算结果表明,该方法操作简便、结果合理,可以满足大多数工程要求。Some works are often asked to consider the influence of the pressure of pore water in seepage on structural stability, so we use the method of the coupling of flow and structure calculation. This paper attempts to calculate a three-dimensional flow field in ANSYS software with technology of ＂life and death＂ and adaptive grid, then uses Duncan -Zhang principle to establish the mathematical model for stress calculation, and adopts the initial stress method for three-dimensional stress field and the seepage field calculation of the indirect coupling. The results show that the method is simple, and the result is reasonable. The method can meet most engineering requirements.
