This paper analyses the research theories and methods of cascade failure at home and abroad. By considering the characteristics of multimodal transportation in Sichuan-Tibet region, the concept of node relevance and collaboration are proposed to replace the traditional concept of node degree. Logit model is introduced to calculate the initial load of nodes. On the basis of node overload mode, this paper presents a method of load redistribution based on local distribution and global-local distribution. The cascade failure problem of multimodal transport network in Sichuan-Tibet region is simulated under different parameters. The results show that the multimodal transport network of Sichuan-Tibet region can withstand the overload load proportion between 50% and 70%, and the node's tolerance factor should be between 0.3 and 0.5.The global-local distribution method minimizes the effects of node overload.
