| Earth dam is an old hydraulic construction. It is also the highest type of dams in the world. Earth dam has the advantages of lower requirement to terrain conditions and less cost. More and more scientists are engaged in researching it. The security of earth dams is always the hot top and the serious seepage is the most important influence factor in all factors resulting in the earth dam destruction. In our country, many hydraulic structures constructed in 1950's or 1960's were constructed in scarcity of technology and economy. All sorts of problems have appeared in working of many years. It is necessary to estimate and study them once more. The analysis of seepage through earth dams is evolved by the reason of above. In this paper, the finite element method is adopted to analyze the 2-D steady and unsteady seepage of earth dams and the program about it is built. There are many examples studied with other methods in documents. In this paper, the same examples are calculated in the program developed by writer .To compared the result of this paper and the documents' ,the veracity of the program is proved. In the end, the main dam of Huangbi-Zhuang reservoir is analyzed with the program built in this paper and some reasonable conclusions are drawn about it. There are also some availability suggestions proposed to estimating and inspecting the earth dams and the problems that to be further studied are presented.
