Study on the Leakage Damage Mechanism and Repair Technology of Shangmaji Weir

Abstract

As a type of dam with a long history and a wide range in the construction of water conservancy projects in my country, weir dams have the functions of flood control, irrigation and diversion. Due to the limitation of construction conditions and environment at that time, the treatment of weir and dam is not standardized enough, which leads to different degrees of problems in weir dam. Based on the example of Shangmaji weir, the article focuses on the analysis of the leakage damage mechanism of the weir, and proposes to choose the corresponding technology to repair it from two angles of the water-facing slope.
