高速公路隧道工程中的超前支护施工技术

Advance Support Construction Technology in Expressway Tunnel Engineering

在公路隧道施工过程中,超前支护施工技术被广泛应用于其中,在该项技术所具备的优势与特点下,能够不断提升地层承载力,降低施工存在的扰动性。基于此,本文以乐业至望谟(乐业段)高速公路项目为例,对超前支护技术进行深入分析,提出应用要点,为相关人员提供参考借鉴。

In the construction process of highway tunnels,the advance support construction technology is widely used.With the advantages and characteristics of this technology,it can continuously improve the bearing capacity of the stratum and reduce the disturbance during construction.Based on this,this article takes the Leye to Wangmo(Leye section)expressway project as an example to conduct in-depth analysis of advance support technology,propose application points,and provide reference for relevant personnel.
