摘要
福州市某电力隧道长度超过6km,沿市政主干道穿行,隧道全线采用3.2m内径顶管铺设。由于地质环境复杂,对土体位移控制要求较高。施工中针对难点问题提出应急方案,为顶管施工的顺利进行提供行之有效的技术解决方案。
An electric power tunnel has cross the main road in Fuzhou, the tunnel is constructed by pipe jacking with 3.2m diameter, and the length is more than 6 kin. Base on the features of this electric power tunnel, pipe jacking and sinking wells, this paper analysis the base principles of design and construction about this project, the analysis of difficult problems of construction has been focused on, and some emergency plans are advised, witch provides many effective solutions for the electric power tunnel construction.
