With the increasing frequency of extreme weather events, distribution networks are facing compounded impacts from typhoon-rainstorm coupled disasters. This paper develops an integrated disaster model that combines wind field simulation with inundation distribution characteristics to quantify failure probabilities of critical nodes and lines. A Monte Carlo approach is employed to simulate the fault evolution and recovery process under typhoon-rainstorm coupling. Based on a multi-dimensional evaluation framework—including load loss rate, critical load outage duration, islanding continuity, and resilience index - the resilience performance of distribution networks is systematically assessed under both single and coupled hazard scenarios. Simulation results indicate that while a single rainstorm has a relatively limited impact, its combination with a typhoon significantly amplifies system losses, particularly in critical node areas. Proper deployment of distributed generation and energy storage can effectively reduce outage duration and enhance overall resilience. This study provides a practical modelling approach and empirical insights for resilience assessment of distribution networks in multi-hazard contexts.
