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。

Conditions of the seepage and stress is a dynamic process, and also shows its interaction and interdependence. Owing to the closure of the fracture, the hydraulic gradient and the permeability pressure of the fracture turn large, and also promote the expansion of water cracks, and fissures connectivity increasing. The increase of the crack opening width will result in the increase of the infiltration capacity and seepage flow, and the reduction of seepage pressure. Because of the dynamic dependence of the fracture aperture, pressure and seepage, under certain conditions, changes in fracture aperture can lead to the formation of local water-passage, and the local emission of high pressure water, and thus promotes the formation of the sudden outgush disasters.

结果表明：洞室开挖完成后，在围岩渗流与应力耦合作用下，围岩中裂隙隙宽、裂隙中水压及其渗透流量的变化是一个动态过程，且相互作用与相互依赖；裂隙的闭合使得结构面水力梯度变大，作用在裂缝上的渗透压力增大，促进导水裂缝扩展，裂隙连通性增加；裂缝张开度增大，渗透能力增强，渗流量增大，其渗流压力相应降低；由于围岩中裂隙隙宽、压力和渗流量的动态依赖性，在一定条件下，裂隙隙宽的改变可导致局部水力通道的形成，高压水头从局部涌出，从而促进突水灾害的形成。

It was shown that the great variation of effective unit weight and angle of internal friction of soil could result in the increase of seepage failure probability of earth dams, the effect of variation of angle of internal friction of soil was greater, and the seepage failure probability of earth dams was sensitive to variability of dam seepage. In addition, the increase of water level in reservoir would also induce great increase of seepage failure probability of earth dams.

结果分析表明，坝体渗透破坏的概率随着土体有效重度和内摩擦角变异性的增加而增加，并且土体内摩擦角的变异性对坝体渗透破坏的影响较大，坝体渗透变异性对坝体渗透破坏的影响较大；另外，随着库水位的升高，坝体发生渗透破坏的概率也显著增加。

The concrete dam displacement is studied considering the factors such as foundation modulus increasing with depth, seepage coefficient reducing as depth, seepage coefficient anisotropic, curtain and drainage in the dam heel and seepage field and stress field coupling. Some conclusions are obtained: if the foundation is considered only with the seepage volume load, the dam top horizontal displacement of the reference base point develops upstream. When the foundation size increases, the reference base point's horizontal displacement increases. However, the value measured by the reversed pendulum anchored to the rock foundation is often regarded to be absolute displacement. The above practice is estimated to be limited when the water load on the dam foundation is taken into account.

分析了地基变形模量随深度逐渐增加、渗透系数随深度逐渐减小、坝基渗透系数各向异性、坝踵设置帷幕排水，以及考虑渗流场和应力场耦合等对混凝土坝位移分量的影响，得出如下结论：作用在地基上的水荷载，使混凝土坝坝顶相对参考基点（倒垂锚固点或坝踵正下方1倍坝高处）的水平位移指向上游，而参考基点的水平位移随地基截取范围的增大而增大，由于大坝工程上常将倒垂线锚固在岩基深处，并认为该倒垂线测值为绝对位移。
