基于珠江口东片网河与伶仃洋多口门衔接水力计算结果 ,提出泥沙计算模型 ,建立了珠江口东片网河与伶仃洋一、二维衔接泥沙数学模型 .结合实测资料对模型进行了调试与验证 ,模拟结果与实测资料基本吻合 .同时对珠江口岸线规划方案进行了预报计算 ,为岸线规划提供了理论依据 ,为一维网河和二维河口规划工程的整体计算研究提供了一种新的数学模拟方法 . Based on the hydraulic calculation results of the multi-port convergence of Wanghe and Lingdingyang in the east of the Pearl River estuary, a sediment calculation model was proposed and a mathematical model of sediment transport in the East and East of the Pearl River Estuary was established. The results of the simulation and the measured data are in good agreement with each other.At the same time, the prediction and calculation of the Pearl River port line planning scheme is carried out, which provides a theoretical basis for the shoreline planning and provides the overall computational study of the one-dimensional network river and two-dimensional estuary planning project A New Method of Mathematical Simulation.
