The research objective is to analyze the seismic resilience change characteristic of urban road network. Firstly, considering the spatial characteristic of earthquake and the comprehensive earthquake damage of road infrastructures, a link connectivity probability model based on intensity attenuation distribution was constructed, thus vulnerable sections were identified. Then, the seismic resilience of specific network under different scenarios was analyzed using a network structural resilience assessment model which considered 3 dimensions. Evaluation results of the effects of these vulnerable links elimination in the network show that network resilience was still strong when a few roads cancelled, while this ability was significantly getting poor after the cumulative attack on the other vulnerable sections. Therefore, network transportation efficiency was reduced, and the connection between nodes were weakened.
