Abstract

Recently there has been rapid development of large-span and shallow-buried highway tunnel construction and considerable risk appear, the urgent issues are that how to identify effectively risk factors which in the process of tunnel construction. With the review of disadvantages of risk recognition methods, the risk hierarchical structure for construction of the tunnel was established using the Analytic Hierarchy Process in a tunnel construction site, the synthesis weights of each basic risk event and weights of factors which cause these basic risk events were calculated. A risk recognition model of large-span and shallow-buried highway tunnel construction was established.
