盾构隧道始发过程存在很大的施工风险。上海长江西路隧道浦东段盾构始发工程针对风险采用“分阶段、全过程”的施工控制技术,确保了隧道盾构始发的安全。详细介绍和分析了对盾构始发地基加固施工以及盾构始发风险等采取的监控技术。其经验可供类似工程参考和借鉴。
There is a great risk of construction in the process of shield tunneling. Shanghai Pudong section of the Yangtze River West Road Tunnel shield starting project for risk using “staged, the whole process ” construction control technology to ensure the safety of the tunnel shield origin. This paper introduces and analyzes in detail the monitoring technology adopted for the reinforcement construction of the initial shield foundation and the risk of shield initiation. Its experience can be used for reference for similar projects.
