Since the emergence of business software to solve a considerable number of difficulties, for the threedimensional dambreak studies have been facilitated.Based on mercial software FLUENT twodimensional and three dimensional of dambreak flow were simulated, the main elements of simulation are as follows:①The whole discharged process of twodimensional dambreak flood used experimental model was simulated in laminar and different turbulent modes, analysed and pared with the experimental results in all of the flow field to find a turbulent model in good agreement with the experimental data.②The whole discharged process twodimensional dambreak broken different ways were simulated with selected turbulent model and analyze the situation by all the flow field.③Using the selected turbulent model simulated the discharged process of the threedimensional dambreak flood and will be analyzed and pared with the experimental results in various time periods.Through this numerical simulation and analysis, obtained the following conclusions:①Simulated the whole twodimensional dambreak flood with experimental model in five different turbulence and laminar models, results of the kεmodel are in good agreement with the experimental with experimental results,the advanced distance over time of the flood striker and the evolution of free surface is very good.②In order to further study the spread of dambreak
