The invention discloses a post-earthquake urban road network restoration time sequence optimization method based on toughness evaluation, and the method comprises the following steps: S1, determining a target urban traffic road network structure, and obtaining the earthquake damage condition of a target road network; s2, damaged road sections are confirmed, and the to-be-repaired road sections are sorted and numbered; s3, in combination with the constraint conditions, the repair time of each road section to be repaired is calculated; s4, determining each node weight and node connection efficiency of the target road network, and calculating a road network performance index; s5, establishing a target function by taking the optimal road network toughness as a target; and S6, judging whether an island exists in the target road network or not, and solving the target function through a genetic algorithm to obtain an optimal repair time sequence. According to the method, under the constraint conditions of limited time, resources and the like, key road sections of islands are preferentially repaired and eliminated, traffic recovery work is rapidly organized, post-disaster loss is reduced as much as possible, the network recovery effect is better, and theoretical support is provided for emergency management.
