Abstract

Dam plays an important role in the development of economy, measurement of flooding, human life and property safety. If dam broken occurs, it could cause massive damage and casualties. Seepage is one of the main problems that influence the dam safety. Therefore, it’s significant to study the dam safety and seepage control measurements. This research focuses on the factors that affecting dam safety and evaluate the seepage fold control methods. Results show that the influence factors of dam safety include geological condition, overtopping, human factors and dam structure. They affect dam safety by causing geological hazards like flood or reducing the dam's ability to withstand these disasters. Seepage prevention and control is effective to alleviate dam safety problems. There are some methods such as concrete impermeable panel, concrete impermeable wall and improvement of dam body. Different measures are applied in different kinds of dam and have specific features.
