Abstract:
In response to the problem of insufficient attention to the risk degree of potential inundation areas in thesiting of shelters for dam failure floods, a new model for evaluating the sites of shelters was proposed. On the basisof establishing the risk evaluation index system, the improved catastrophe theory evaluation method was used to evaluate the risk degree and classify the risk level of the potential inundation areas. The distance between sheltersand high-risk level areas was taken as the site selection evaluation index, and the disaster risk, location scale, emergency support of shelters were considered. The weights were determined by AHP method, and the TOPSISmethod was applied to evaluate the sites of shelters. Finally, 13 potential inundation areas and 10 alternative shelters downstream of Luhun Reservoir in China were used as examples for validation. The results showed that amongthe areas with high risk levels, Baiyuan Township was a Class Ⅰ hazardous area, and Pengpo Township, MinggaoTownship, Chengguan Street, and Longmen Township were Class Ⅱ hazardous areas. The better evaluated shelterscould meet the requirements of paying attention to areas with high risk degree.
