摘　　要：针对平面形态对内河挖入式港池水沙特性的影响,借助丹麦DHI公司开发的MIKE二维水沙数学模型,从港池口门宽度、以及主流与港池中轴交角两个方面出发,通过建立对比数模分析研究,对这些因子变化引起港池水沙特性影响进行定性分析,结果表明,随着口门增大,港池内的泥沙淤积规模先增后减,同时,中轴与主流交角的偏移,无论从正向或者逆向,都会导致港池内泥沙淤积量的增大.该结论可供同类研究借鉴.Based on the influence of sediment characteristics of planar form for inland waterway excavated harbor, with the help of MIKE two-dimensional mathematical model of water and sediment developed by Danish company DHI, qualitative a- nalysis is conducted through the establishment of contrast analog analysis on sediment characteristics influenced by changing factors, such as the dock entrance width, as well as the mainstream and basin axial angle. The research results show as the entrance increases, sediment deposition in the basin increase after decreasing first, at the same time, the central axis and the mainstream of migration, no matter from the positive or the negative, lead to the increase of sediment deposition in the basin. This research conclusion offers some reference to the similar research.
