摘要
上海市轨道交通L18一期工程两港φ3 000 mm合流截流污水总管改迁后需近距离下穿现有高危居民住宅,通过总结盾构施工过程中建筑物的沉降规律,严格控制盾构穿越施工参数,并在施工过程中采取Clay-shock工法减少构筑物沉降,相关经验可为类似工程的施工提供参考。
With the background of Shanghai Rail Transit L18 Project(Phase I), the confluent &intercepting sewage pipe of two harbors withφ3 000 mm should underneath pass the existing high-risk residential buildings. By summing up the laws of building settlement during the shield construction,the construction parameters are strictly controlled and the Clay-Shock method is adopted to reduce the structure settlement during the construction process. The related experience can provide reference for similar projects.
