摘　　要：依据桥梁的数学模型试验结果及资料,分析探讨了桥梁建设对桥区水动力的影响,结果表明,桥梁建设对水流的影响主要表现在桥墩附近,并且桥墩的存在对水流的影响具有双向性。涨落潮时桥墩的迎水面水位壅高,背水面水位降低,并且壅高和降低值随着距桥址距离的增加而减小。Based on the mathematical model test results and data of the bridge, the influence of the bridge construction on the hydrodynamic force is analyzed and discussed. The results show that the influence of the construction of the bridge on the water flow is mainly in the vicinity of the bridge pier and the influence of the bridge pier on the water flow is bidirectional. When tide flows and ebbs the surface of the water level increases, the back surface of the water level decreases, and the value of increase and decrease decreases with the increase of the distance between the bridge and the bridge.
