超前支护施工技术在高速公路隧道施工中的应用

Application of Advance Support Construction Technology in Expressway Tunnel Construction

超前支护施工技术在预防隧道围岩变形方面发挥了重要作用,同时还在很大程度上提升了围岩的支护力,以免施工对围岩产生干扰,使隧道结构的安全性也得到可靠保障。因此,文章在分析超前支护施工技术优缺点的基础上,对导向墙施工技术、大管棚支护施工技术、超前小导管支护施工技术这三种超前支护施工技术在高速公路隧道施工过程中的具体应用进行分析,以期为施工人员提供参考。

The advance support construction technology plays an important role in preventing the deformation of tunnel surrounding rocks. At the same time, it also greatly improves the support force of surrounding rocks, so as to avoid the interference of construction on surrounding rocks and ensure the safety of tunnel structure. Therefore, on the basis of analyzing the advantages and disadvantages of advance support construction technology, this paper analyzes the specific application of three advance support construction technologies, namely, guide wall construction technology, large pipe shed support construction technology and advance ductule support construction technology, in the construction process of expressway tunnel, in order to provide references for construction personnel.
