摘要
基于近年来软弱围岩隧道变形坍方多个实例,分类浅析了引起隧道变形、坍方的原因,提出了针对性的控制围岩、支护变形和防止坍方的措施。
Based on the examples of soft rock tunnel deformation and collapse in recent years, classification of tunnel col- lapse, reasons for deformation are discussed and measures to control surrounding rocks, to support deformation and to pre- vent collapse are pu~, forward.
