The New Century Bridge will be built across Xiliao River. The construction of the bridge increases the complexity of water flow condition of Xiliao River. By establishing the mathematical model and adopting the form of finite element mesh dissection, the distribution of the maximum depth of flood water, the maximum flow velocity and the highest water level for flood in front of the dam and bridge are simulated before and after the bridge built to judge flow pattern effectively. By establishing a numerical model of flow pattern, which plays a decisive role for bridge abutment protective, depth of the pile foundation and pile caps, and has the greatest impact for next structure optimization of the bridge.
