摘　　要：为研究灌河口各整治工程实施后对河口纳潮量、潮位、流速的影响并提出最优的灌河口整治方案,首先分析了灌河口的自然条件;然后构建二维水流数学模型,根据实测资料对模型进行验证;最后利用数学模型对各整治方案实施前后的水力特性变化进行分析。口门整治工程实施后结果表明:仅导堤工程的实施对河口纳潮量影响较大,应配合航道疏浚工程来缓解其带来的影响;导堤工程和航道工程同时实施后,双导堤内水流进一步归顺,流速有所增大,对维持航道水深较有利。To predict the impact of regulation project on the tidal prism, tidal level and velocity at the Guanhe estuary and provide the optimal regulation plan of the Guanhe estuary, we analyze the natural conditions of the estuary firstly, then build a two-dimensional mathematical model, which is verified by measured filed data, and finally analyze the changes of hydraulic characteristics after the project by the mathematical model. The result shows that waterway dredging project should be carried out with the regulation project because leading jetties can decrease the tidal prism significantly; After implementation of the leading jetty engineering and waterway engineering, the velocity of the flow between the double jetties increases.
