摘　　要：钻爆是采矿和隧道掘进中广泛使用的开挖方法,特别是在硬岩条件下。由于钻爆法施工工序复杂,爆破会造成围岩的扰动,从而导致隧道的坍塌。隧道塌方灾害成为隧道建设中的一个关键问题,必须对其进行充分分析,以防止经济损失和人员伤亡。研究基于量化分级体系和显著影响隧道塌方危险性的影响因素,进行了隧道塌方危险性分析,并根据其风险源提出相对应的处理措施。文章可为后续的地貌相似的公路隧道坍塌提供一些参考。Drilling and blasting are the widely used excavation method in mining and tunnel excavation,especially in hard rock conditions.Due to the complex construction process of drilling and blasting method,blasting will cause disturbance of surrounding rock,which will lead to tuimel collapse.Tunnel collapse disaster has become a key problem in tunnel construction,and it must be fijlly analyzed to prevent economic losses and casualties.Based on the quantitative grading system and the influencing fectors that significantly affect the risk of tunnel collapse,this study analyzes the risk of tunnel collapse,and puts forward corresponding treatment measures according to its risk sources.This article can provide some reference and help for the subsequent collapse of highway tunnels with similar landforms.
