摘要
文章通过对连拱隧道先中导洞开挖、中隔墙混凝土灌注、中隔墙顶部混凝土回填、中隔墙防偏压处理等方面的介绍,总结了双跨连拱隧道先中隔墙施工后正洞掘进的一些经验。
In this paper, some experience on CRD method prior to main tunnel excavation are summarized, which is characterized by the sequence of medium pilot excavation, concrete pouring, top back -filling and the countermeasures against bias pressure during the construction of tunnel with double continuous spans.
