摘要
结合工程实例,围绕水平层状软岩大断面小净距隧道关键施工技术展开探讨.首先介绍了隧道的主要工程背景.其次分别介绍了隧道单侧壁导坑法施工和双侧壁导坑法施工的详细施工流程与施工要求,并提出应急预案处治措施,结合隧道特点,提出了隧道施工过程中应具体监控量测的内容.最后从施工安全设计方面提出具体针对措施,可为同类型隧道项目提供借鉴.
Abstract
Combined with engineering examples,this paper discusses the key construction technology of large-section and small-spacing tunnels in horizontal layered soft rock.Firstly,it introduces the main engineering back-ground of the tunnel.Then,it introduces the detailed process and requirements of the construction of the single-side guide pit method and the double-side guide pit method of the tunnel respectively,and puts forward the treatment measure of emergency plans.Combined with the characteristics of the tunnel,it puts forward the content that should be monitored and measured specifically in the process of tunnel construction.Finally,it puts forward specific targeted measures from the aspect of construction safety design,which can provide reference for similar tunnel projects.
