隧道洞口不良地质段的施工技术研究

Study on the Construction Technology of the Tunnel Portal in Unfavorable Geological Section

隧道工程施工中,如果洞口处于不良地质段,会对工程整体施工效果产生直接影响,要求施工单位必须切实做好不良地质段的处理工作,选择恰当的施工技术和施工方法来保证隧道洞口顺利施工。论文结合具体工程案例,从隧道洞口的特点出发,对隧道洞口不良地质段施工技术进行了分析和研究,希望能为类似工程的施工提供借鉴。

In tunnel engineering construction,if the portal is in a bad geological section,it will have a direct impact on the overall construction effect of the project.It is required that the construction unit must do a good job in the treatment of bad geological section and choose the appropriate construction technology and construction method to ensure the smooth construction of the tunnel entrance.Based on concrete engineering cases,this paper starts from the characteristics of the tunnel entrance,analyzes and studies the construction technology of the bad geological section engineering cases,hoping to provide reference for the construction of similar projects.
