【Abstract】The geographical conditions of barrier lakes in mountainous areas are complex and changeable, and the time and scope of dam break are uncertain and the places of refuge are not enough. This paper proposes a method applying for selecting refuge of barrier lakes in mountainous areas, based on the simulation results of dam-break flood routing. Combined with the regional geographical conditions of barrier lakes, this method uses the analytic hierarchy to flexibly distribute the weight value and determines the scoring standard according to the empirical theory. Based on the inundation data obtained by the simulation program and regional data of dam-break flood routing, the model of selecting site for refuges in the region of barrier lakes is constructed and the results are calculated. Finally, combined with the simulation results of dam-break flood routing, the maximum utilization time of shelters is analyzed dynamically. With Xiaojiaqiao barrier lake as a case study, this approach can flexibly solve the problem of large environmental differences in barrier lakes, maximize the use of temporary refuge, and provide a scientific basis for the establishment of the emergency plan for barrier lakes.
