公路隧道软岩大变形施工处理技术

Construction Treatment Technology for Large Deformation of Soft Rock inHighway Tunnel

我国经济实力以及科学技术水平的不断提高,使城市化公路建设得到了全面优化和发展,加之人们生活水平日益提升,对交通运输设施的建设效率和质量提出了更高的要求,因此,公路隧道结构方案设计的合理性成为城市基础交通建设的重要元素之一。论文针对目前我国常见的公路隧道设计方案进行综合阐述,并根据隧道软岩所产生的形变问题进行进一步探索,总结注浆固结以及支护施工阶段公路隧道软岩大变形施工应对策略。

With the continuous improvement of China’s economic strength and scientific and technological level,the construction of urbanization highway has been comprehensively optimized and developed.In addition,people’s living standards are increasingly improved,which puts forward higher requirements for the construction efficiency and quality of transportation facilities.Therefore,the rationality of highway tunnel structure design has become one of the important elements of urban basic transportation construction.In this paper,the common design schemes of highway tunnels in China are comprehensively elaborated,and the deformation problems caused by soft rock in tunnels are further explored,and the countermeasures for large deformation construction of highway tunnels in grouting consolidation and support construction stage are summarized.
