水库设置输水洞为坝下涵管,受到当时修建技术条件的限制,而且维护工作进行较差,致使现在水库输水洞包括竖井在内存在着严重的渗漏以及其他问题,严重影响到大坝的安全运行。通过对水库输水洞竖井存在问题进行调查分析,借鉴国内外输水洞竖井除险加固工程经验,提出可采用的除险加固技术措施,为类似工程建设提供参考。 The water diversion tunnel was set as the culvert under the dam, which was limited by the technical conditions of construction at the time, and the maintenance work was poor. As a result, serious leakage and other problems existed in the reservoir diversion tunnel, including the shaft, seriously affecting the dam Safe operation. Through the investigation and analysis of the existing problems in the water supply shaft of the reservoir, drawing lessons from the experience of domestic and overseas water diversion tunnel shaft reinforcement and reinforcement projects, the technical measures for reinforcement and reinforcement can be put forward to provide reference for the construction of similar projects.
