Abstract：The MIKE21 FM module is two-dimensional hydrodynamic model based on unstructured grid,which can generalize river terrain and road flexible;pier resistance can be processed by sub grid technique. Simulation results can better reflect flow field,velocity,water level in calculated channel and the elements changes surrounding piers. According to the complex topographic features and the uncertain boundary of water resisting at the mouth of the Daling River,the hydrodynamic simulation calculation of multi schemes is carried out,and the variation law of the water level and velocity of the river under different bridge length is analyzed. The study result is a reliable scientific reference for engineering construction and flood control evaluation.
