摘要
在不良地质地段进行隧道建设,其整体稳定性和荷载承受能力较差,对隧道工程的施工和运营安全有着严重的影响,需要采取有效的措施给予解决。以已建高速公路隧道施工为例,对施工遇到的软岩大变形和岩溶等不良地质进行分析并采用相关的处理技术,通过对隧道不良地质地段处理技术应用效果分析,总结施工经验,为相似工程提供技术参考。
The overall stability and load bearing capacity of tunnel construction in unfavorable geological sections are poor,which has a serious impact on the construction and operation safety of tunnel engineering,and effective measures need to be taken to solve it.This paper takes the construction of the existing expressway tunnel as an example,analyzes the soft rock large deformation and karst and other unfavorable geology encountered in the construction and adopts relevant treatment technology.Through the analysis of the application effect of the treatment technology in the unfavorable geological section of the tunnel,summarizes the construction experience,and provides technical reference for similar projects.
