隧道结构及施工薄弱环节分析与防治

摘要

This paper analyzed the tunnel structure and construction situation,pointed out the weak links of tunnel engineering structure and con-struction,and researched the prevention measures of tunnel bottom road collapse,seepage,lining arch support air or cavity and other problems, had certain reference value for the design and construction of tunnel engineering.%对隧道工程结构及施工现状进行了分析，指出了隧道工程结构及施工的薄弱环节，并对隧底路面塌陷、渗漏水、衬砌拱部托空或空洞等问题的防治措施进行了研究，对隧道工程设计及施工具有一定的借鉴作用。
