随着我国大量的高速公路的建设及公路建设技术标准的提升,隧道工程所占比重越来越大,所穿越地层地质条件空前复杂,施工倍受各种地质灾害及自身技术、管理等方面的困扰,施工坍塌现象也愈来来愈频发。本文从分析隧道坍塌致灾因素出发,解析导致隧道坍塌的相关因子,并利用隧道坍塌鱼刺图进行因子解析,讨论坍塌事故发生的原因及可能性;探导降低施工坍塌风险事故的措施,以达到降低隧道工程施工风险,节约工程建设经费,减少社会不良影响的目标。
With the construction of a large number of expressways in our country and the improvement of technical standards for highway construction, the proportion of tunnel engineering is increasing. The geologic conditions of the strata to be traversed are unprecedentedly complicated. Construction is greatly affected by various geological disasters and their own technologies and management. Disturbed, the collapse of the construction is also more and more frequent. Based on the analysis of the causes of tunnel collapse, the paper analyzes the factors that lead to the tunnel collapse, analyzes the causes of the collapse accident and the possibility by using the factorial analysis of the tunnel collapse fishbone map, explores the measures to reduce the risk of construction collapse so as to achieve Reduce the tunnel construction risk, save construction funds, reduce the adverse social impact of the goal.
