复杂地层下穿湖泊顶管施工关键技术分析

Analysis of Key Techniques for Pipe Jacking Construction under Complex Strata through Lakes

摘要: 顶管掘进施工是水利工程中常用的地下工程施工方法，对于复杂地层下穿湖泊顶管施工顶力计算和施工技术要求较高。为此，本文依托珠三角水资源配置工程东莞配套松山湖水厂一期管线工程顶管下穿松山湖工程，采用理论推导方法，计算得到了顶管顶力值，验证了施工的安全性，阐述了顶管掘进施工关键技术，为类似工程提供参考。

Abstract: Pipe jacking construction is a commonly used underground engineering construction method in hydraulic engineering, which requires high requirements for the calculation of jacking force and construction technology for pipe jacking construction in complex formations that penetrate lakes. Therefore, this article relies on the Pearl River Delta Water Resource Allocation Project Dongguan Matched Songshan Lake Water Plant Phase I Pipeline Project for Pipe Jacking and Undercrossing Songshan Lake. The theoretical derivation method is used to calculate the value of pipe jacking force, verifies the safety of construction, and the key technology of pipe jacking excavation construction is elaborated, providing a reference for similar projects.
