Based on the precipitation observation data from meteorological stations in Zhejiang Province during 2006-2017 and combined with the geographic information and social and economic data, the risk assessment index sets were established on the basis of the analysis of hazard factors, vulnerability and exposure, considering the natural geographical environment characteristics of expressway. Risk assessment model was established by using methods of ArcGIS spatial technique and fuzzy comprehensive evaluation method, and finally the risk division map of rainstorm disasters on expressway in Zhejiang was performed. The results show that the higher level of rainstorm risk appeared in southeast coastal areas and west mountainous areas of Zhejiang, while the lower level of rainstorm risk on the expressway sections occurred in the north of northern Zhejiang and central basin area.The higher risk sections were mainly located in Chang-Shen expressway Fuyang section, Jing-Tai expressway Kaihua sections, Zhu-Yong expressway Yongjia sections, Wen-Li expressway Wenzhou sections, Wenzhou ring expressway,Yong-Tai-Wen expressway Taizhou section, and from Ruian to Cangnan sections,Chang-Tai expressway Tiantai east sections.
