摘　　要：马颊河为山东省海河流域的主要排水河道,由于海洋泥沙运动的特性,其入海口处泥沙回流淤积。运用数学模拟手段,建立了马颊河河口二维非恒定流水沙数学模型,并根据实测地形、水文资料进行了水流、泥沙模型验证,根据马颊河河口特点和清淤长度、宽度、深度与回淤率之间的关系,拟定了不同的河道整治方案,并对不同方案的泄量、回淤量进行了模拟分析,选出了最优方案。Majia River is a main drainage river of Haihe river basin in Shandong Province and mud sedlmentanon oc- curs at the estuary because of the characteristics of water and sediment movement. Numerical simulation method is adopt- ed to establish 2-D unsteady water-sediment mathematical model of Majia Estuary. And the hydraulic dynamics and mud transportation of the model are verified by using the measured topography and hydrology data. Then different dredging plans are proposed after considering the features of the estuary and the relationship among the length, width, depth and back-silting rate of the dredging plan. Finally, the discharge and back-silting amount of the dredging plans are analyzed and the optimal scheme is determined.
