This paper considers coupling the formula proposed by the Railway Research Institute and Xie Renzhi's gradual dam break model, and puts forward an improved barrier lake's gradual dam break model. After simulating the dam break flood of the “11.3” Baige barrier lake in Jinshajiang basin, it is found that the simulation results are similar to the measured rise duration and post-peak duration, and the error range does not exceed 5%, and the pre-peak and post-peak water discharge is less than 15% compared with the actual measurement. The practicality of the proposed model is verified by this example, and it can be used for the rapid calculation of the dam break flood.
