With the rapid development of highway tunnel construction in China,tunnel projects are facing various geological disaster risks.The collapse tunnel surrounding rock is a major geological disaster in tunnel construction.This article combines cases of collapse geological disasters with different origins,refers to relevant specifications and relevant literature,and uses statistical analysis methods to propose the risk factors that cause surrounding rock collapse.Various risk factors are used to establish the membership function of risk factors for the probability of occurrence of the disaster.A set of comprehensive analysis methods for collapse geo-hazard was proposed.Taking the Fuling area of Anhui Province as an example,a comprehensive assessment of geological hazards is conducted.Compared with construction monitoring results,the assessment results are relatively consistent with the monitored results.
