随着我国交通建设的快速发展,山岭隧道建设中高地应力软岩不良地质情况屡屡发生。高地应力软岩隧道变形大、处理风险高、工期时间长,有效预防和控制隧道大变形成为目前隧道建设中亟需解决的问题。对高地应力软岩隧道特点进行总结,揭示高地应力条件下隧道大变形产生机理及影响因素,研究高地应力软岩地质条件下变形控制技术,并在实际工程中得到成功应用。研究结果对高应力软岩条件下隧道施工具有重要指导和借鉴意义。
With the rapid development of traffic construction in our country, the adverse geological conditions of high stress and soft rock in mountain tunnel construction often occur. High-stress soft rock tunnel deformation, high processing risk, long duration, effective prevention and control of tunnel deformation has become an urgent need to solve the problem of the current tunnel construction. This paper summarizes the characteristics of high stress soft rock tunnel, reveals the mechanism and influencing factors of large deformation of tunnel under high ground stress, studies the deformation control technology in high ground stress soft rock geological conditions, and successfully applies in practical engineering. The results provide important guidance and reference for tunnel construction under high stress and soft rock conditions.
