摘　　要：随着高坝大库建成投产及长期运行,水下水工建筑物或多或少存在不同程度的缺陷,为确保水工建筑物安全稳定运行,需进行水下检测和修复,特别是超深超长隧洞水下修复加固处理亟待解决。对水下检测及修复加固技术进行研究,阐述各种水下检测方法的优缺点及适用范围和100 m以内水下修复加固处理方法,首次提出超深超长隧洞水下修复加固采用ADS常压潜水系统进行水下作业,为解决类似问题指明研究方向,成功运用将填补国内外空白。With the completion and long-term operation of the large reservoir of high dams,underwater hydraulic structures have more or less defects in varying degrees.In order to ensure the safe and stable operation of hydraulic structures,it is necessary to carry out underwater detection and repair,especially the underwater repair and reinforcement of ultra-deep and ultra-long tunnels need to be solved.This paper studies the underwater detection and repair and reinforcement technology,expounds the advantages and disadvantages and applicable scope of various underwater detection methods and the underwater repair and reinforcement methods within 100 m,and puts forward for the first time that the underwater repair and reinforcement of ultra-deep and ultra-long tunnel adopts ADS atmospheric pressure diving system for underwater operation,which points out the research direction for solving similar problems,and the successful application will fill the gap at home and abroad.
