公路隧道软弱围岩开挖处理方法研究

Study on Excavation Treatment Method of Soft Surrounding Rock in Highway Tunnel

软弱围岩具有地质松软、易塌陷以及稳定性差的特点,属于公路隧道工程施工建设过程中较为棘手的一个问题。所以在软弱围岩地段开展公路隧道施工作业时,需要切实结合施工环境以及施工条件等来科学选择最为适宜的施工方案,降低施工风险。以某工程为例,针对公路隧道软弱围岩开挖处理方法进行了分析和探讨,以解决公路隧道工程中的软弱围岩难题。

As for soft surrounding rock,it has the characteristics of soft geology,easy collapse and poor stability,which is a thorny problem in the actual construction process of highway tunnel engineering.Therefore,when highway tunnel construction is carried out in soft surrounding rock sections,it is necessary to scientifically select the most appropriate construction scheme in combination with the construction environment and construction conditions to reduce construction risks.Based on this,the article will take a project as an example to analyze and discuss the excavation treatment methods for soft surrounding rock of highway tunnel,so as to promote the continuous development of highway tunnel construction.
