Abstract

Seepage of dam foundation area and reservoirs are considerable problems that most of these structures are involved with. Escape of water from reservoirs, the possibility to create high pressure (uplift pressure), underground water level control, increasing the volume of water pumping from project area and consequently increasing administrative costs and reducing efficiency are the most important problems. Sangtuda 2 Dam and Power plant Project is one of the ninth serial dams that are constructed over the Vakhsh River, one of the Amudarya branches. This dam is under construction, due to its location on the lime stone layers and due to the high karstification and Tectonics situation at run time encountered with lots of water leakage and overflow in spillway and power plant area. Water outflow increased up to 8 cubic meters per second at the time being. The water rate increase administrative costs (due to high costs of pumping water from the pit, sharp reduction in work efficiency an...). This article reviews the status of geology, hydrological, Tectonic and geotectonic in project area. Maximum water volume estimation in the possible ranges is established numerically by software to achieve perfect solutions. Solving methods and reviews the results indicates the need to pump about 10 cubic meters per second from the plant bed (level 450). Keywords: Sangtuda2, Tajikistan, pumping, Karistification, leakage.
