本文利用七○年至七九年,黄浦江各码头原始疏浚资料和测量资料,将黄浦江按自然弯曲形态划分凹、凸和过渡段,并定性地讨论了各河段的一般回淤特征,找出了与回淤速度直接有关的相关因子,借助回归分析,建立了定量推算泥沙回淤量的方程,用以预测各码头的回淤速度,为码头的计划管理提供了依据。
Based on the original dredging data and measurement data of the wharfs of the Huangpu River from 1970 to 1979, the paper classifies the Huangpu River into concave, convex and transitional segments according to the natural bending pattern. The characteristics of general silt deposition in each river segment are qualitatively discussed. The correlation factors directly related to siltation rate were found out. With the help of regression analysis, an equation was established to quantitatively calculate silt siltation, which could be used to predict the siltation rate of each silo, which provided the basis for the planning and management of the pier.
