Abstract: As the first large-scale reservoir built in Hubei Province, Shimen reservoir was designed with high and low conduit pipes crossing through the dam. However, perils on the low conduit pipe are existing and threatening the salty of the dam. In this paper, based on the field survey and structure calculation, steel lining in conjunction with self-hold anchor rod are adopted to reinforce the low conduit pipe after various options compares, which provide agood solution for the reinforcement of conduit pipes for those reservoirs with safety problems.

摘要： 石门水库是湖北省兴建的第一座大型水库，穿坝布置有高、低输水管，低输水管存在诸多安全隐患。本文从现场检测和结构计算出发，通过方案比选，采用自锁锚杆+钢板方案对低输水管进行了加固设计，为病险水库输水管的加固提供了有益的思路。
