摘要
介绍了上海西藏路电力隧道工程概况,重点论述了工程顶管施工的三维复合小曲率半径、轴线变化较大,以及穿越复杂地下管线、地铁、地表变形要求高等特点和难点。为大口径三维曲线顶管在大城市繁华地段施工和环境保护提供了理论依据和实例。
IThe paper introduces the general situation of Xizang Road Power Tunnel Project in Shanghai City, and mainly states the characteristics and difficulties such as three-dimensional composite small curve diameter, greater variation of a-xis, high requirements for passing through complex underground piping, metro, surface deformation of the project jacking construction. It also provides the theory basis and example for the construction of large orifice three-dimensional curve jacking in busy plot of big cities diameter and the environmental protection.
