摘要
介绍软弱围岩受地质构造作用,在隧道施工中产生大变形的机理和特点。根据现场施工情况,总结运用常规施工手段控制变形的施工措施,为类似地质条件下的隧道施工控制大变形的出现提供参考。
This paper introduces the mechanism and characteristics of large deformation of weak surrounding rock under the role of geological structure in tunnel construction. According to the experience gained at construction sites, the authors sum up the measures of using conventional construction methods to control deformation, and provide the reference to the control of large deformation in tunnel construction under similar geological conditions.
