摘要：

this paper studied urban road waterlog risk problem of Handan based on the two-dimensional information diffusion model, fist to collected original data including distribution of waterlog spots, raining strength, waterlog history, danger sources and risk bearing objects with the joint of meteorology department, municipal drainage department and social communities, then to construct relationship model between indexes of raining strength and waterlog depth for each of waterlog spots. With a certain raining strength, the model can give a waterlog depth prediction of the waterlog spot, and then it can estimate risk scenarios for each of the risk bearing objects with the spot. Studies show that, the information diffusion method for urban road waterlog risk evaluation problem proposed in this paper, has a certain application value for plain cities' urban waterlog problem.
