Abstract:
Building dam is very rapidly developing in Iran; then caring the technical points will help us to maintain their firmness and strength and also use it in suitable manor. One of the problems of soil dams in the world is the seepage and leaking phenomena. The problem of leaking of water and the ways of controlling the leakage in soil dams is one of the most important technical problems in designing, building, well maintaining and use of soil dams. In this analysis, hydraulic circulation in spongy environments and numeral methods of solving equation of water circulation in saturated soils was analyzed and then leakage analysis was performed using mathematical models. Finally, analyzing of applied model was conducted using Flac d, Seep/w2d software. The soil dam of Gotvand Olya was considered as special study and the amounts of leakages in heights of 135, 150, 185, 209, 230, 234 and 244, were analyzed. Data at the height of 135,150,185 were compared. In conclusions using exact tools it was found that the obtained results of Flac2d software was more precise than Seep/w2d software.
