Abstract

Abstract

According to the engineering construction characteristic of freeway tunnels, some methods were adopted to investigate and predict the geological condition of tunnel wall rock on the basis of dynamic wall rock classification. The information obtained by these methods was integratively analyzed and optimized so as to evaluate the dynamic stability of expressway tunnels. The results of practical application show that this evaluation method is simple and effective.
