分析了海河河道特性、来水变化及发展趋势，海河口泥沙淤积状况，纵横断面以及拦门沙发展变化，总结了海河口挖泥疏浚的经验教训．利用物理模型试验方法，研究了海河口现状条件泄流过程以及最大泄流能力，根据海河口近几年的实际清淤能力，研究了海河口不同清淤方案和清淤方式的清淤效果、海河闸泄流能力和闸上水位，并进行了不同清淤方案和方式的对比分析，为海河口清淤疏浚提供了一定的科学依据，同时也为其它大江大河挖泥疏浚提供了参考．
Analysis of the characteristics of the Haihe River, incoming water changes and trends, sediment deposition in the Haihe River estuary, vertical and horizontal sections and the development of sand bar development, summed up the Haihekou dredging experience. Based on the actual dredging capacity of Haihe Estuary in recent years, the dredging effect of different dredging schemes and dredging methods of the Haihe River estuary was studied using the physical model test method. Haihe River sluice discharge capacity and water level on the gate, and carried out a comparative analysis of different dredging programs and methods for the dredging of the Haihe River estuary dredging provides a scientific basis, but also for other major river dredging dredging provides a reference.
