摘要
鉴于巴拉水电站特大断面隧洞的开挖支护与混凝土衬砌位于关键线路上,其均占用直线工期,在施工过程中会因各种原因造成工期滞后。阐述了为解决工期滞后问题采取的在隧洞开挖与支护的同时进行边顶拱混凝土衬砌施工技术,实现了开挖支护与混凝土衬砌平行作业,进而加快了施工进度,确保了总工期的实现。
Given that the excavation and support,as well as the concrete lining of the extra-large section tunnel in Bala Hydropower Project,are both located on the critical route and occupy a linear construction period.During the construction process,various factors may cause delays in the project schedule.To solve the problem of delayed construction period,the construction technology of side and top arch concrete lining has been adopted while excavating and supporting the tunnel,achieving parallel operation of excavation support and concrete lining,thereby accelerating the construction progress and ensuring the realization of the total construction period.
