摘要
Abstract
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.Dur-ing 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 lin-ing,thereby accelerating the construction progress and ensuring the realization of the total construction period.关键词
