摘　　要：文章以珠江隧道为例,首先对水封隧道渗漏的原因进行了分析,介绍了隧道检修流程,然后就隧道渗漏检测、管片及壁后空洞检测技术要点展开了详细的研究,获得了隧道主体的缺陷数据,并提出维修建议,为制订水封隧道检修维护方案提供了指导。Taking the Pearl River Tunnel as an example, this paper first analyzes the reasons for the leakage of the water-sealed tunnel, and introduces the tunnel maintenance process. Then, it conducts a detailed study on the technical points of tunnel leakage detection, segment and cavity detection behind the wall, obtains the defect data of the tunnel body, and puts forward maintenance suggestions, which provides guidance for formulating the maintenance scheme of the water-sealed tunnel.
