摘　　要：长江下游岸边取排水工程大多采用顶管施工工艺穿越长江大堤,顶管施工对地基土的强烈扰动严重威胁大堤的完整性、稳定性和安全性。为了确保大堤安全,必须开展顶管施工期间和工后的长江大堤安全监测。文中在分析了顶管施工对大堤安全影响的基础上,针对此类工程的特点,系统地阐述了大堤安全监测技术的内容和方法,并结合某电厂一期工程介绍长江大堤安全监测技术的应用。实践证明,文中阐述的理论和方法是正确、可行的。The technique of pipe jacking has been widely applied to water supply and drainage projects on the lower reaches of the Yangtze River; however, the integrality, stability and safety of the Yangtze levee are threatened by the disturbance to the foundation soil. In order to ensure the safety of the Yangtze levee, safety monitoring during pipe jacking and afterwards is necessary, Based on the analysis of the pipe jacking effect, the levee safety monitoring technology is expounded systematically. With a project as an example, the method is proved feasible.
