摘　　要：深厚覆盖层是一种地质复杂、结构条件差的地基,对大坝的渗流起着至关重要的作用。文章将连续介质渗流应力耦合开发程序应用到实际工程中,将研究对象看做连续介质进行渗流场与应力场耦合研究,进行3种工况下的计算,并对三种工况的计算结果进行详细对比分析。结论表明在实际工程中考虑渗流应力耦合必要性和合理性。Deep overburden is a kind of foundation with complicated geological structure and poor condition and it plays an important role in the seepage flow of the dam.In this paper,the coupled development program of seepage stress in continuous media is applied to practical projects,the seepage field and stress field are coupled as a continuous medium to carry out the calculation under three working conditions,and the calculation results of the three working conditions are compared and analyzed in detail.The conclusion shows that it is necessary and reasonable to consider the coupling of seepage stress in practical engineering.
