Abstract
Road traffic is an important access for emergency service and disaster relief after the earthquake. In this paper, a reinforce-optimization model for road network seismic is established in combination with the analysis results of the seismic reliability of road segment and the importance of road segment. The model is aimed at the lowest cost of reinforcement and optimization, ensuring the aseismic reliability of the road segment and the system to reach the lowest limited value after the reinforcement and optimization, and the highest reliability of the system is mainly considered after the reinforcement and optimization. The orthogonal enumeration method is used to solve the scheme which satisfies the model condition, and a design method for seismic reinforcement and optimization of road network is given. Finally, it confirms the feasibility of this method with an example.
