摘要
基于成兰铁路杨家坪出口三线大跨段隧道的复杂地质条件,提出了双侧壁导坑法的成套施工方法,阐述了具体的施工工艺,并进行了监控量测,实践表明该施工方法确保了三线大跨段的安全施工,加快了施工进度,在工程中应用达到了预期效果。
Based on the complex geological conditions of Chenglan Railway Yangjiaping export three line large span tunnel,this paper proposed the sets of construction method of double sidewall drift method,elaborated specific construction technology,and made monitoring and measuring, the practice showed that the construction method ensured that the safety construction of three line large span section,to speed up the construction progress and reached expected effect in engineering application.
