Evaluation method of highway quality and safety based on finite element analysis

With the continuous advancement of China's transportation infrastructure, number and proportion highway tunnels in expressway construction are increasing year by year. In order to accurately evaluate quality safety tunnel engineering, finite element analysis is used secondary lining structure, slotting method analyze working stress load on structure inversely analyzed combined with three-dimensional model structure. The test results show that error rate deduced combining 2.22%, average vertical uniformly distributed two lane three 7.09%, horizontal lateral pressure coefficient 16.37%. numerical errors within acceptable accuracy range actual engineering. Using can provide effective data reference for evaluation defect reinforcement
