According to the mathematical model of saturated-unsaturated instantaneous seepage, the paper has considered the effects of different unsaturated parameters within an element and solved the problem of unstable calculation caused by sudden changes of boundary condition in a saturated zone by using the method of Gauss point. The paper has also introduced the relative study of TSAP programme and made two dimentional seepage analysis for some parts of the Yellow River embankments by using the programme. The result of calculation is basically the same as the seepage status reflected by the observed data, showing the effectivity, practicality and reliability of TSAP programme and its adopted theory.

According to the hydrogeologic features at the site of the Second Stage Cofferdam of the Three Gorges Project and the assumption that there exist some faults in the seepage prevention wall (SPW) of the cofferdam, a saturated and unsaturated seepage calculation model is presented in this paper and the special 3 D multifunction FEM seepage program is worked out. The model is firstly used in the calculation when some faults located on the upper, middle or the lower part of SPW are considered. From the calculating results, the different seepage distributions and the influence of various factors, such as the unsaturated parameter, the location of faults, the size of faults and so on, are analysed. Thus the seepage stability of the cofferdam with some parital faults in SPW is reviewed.
