摘要
本文试用统计学方法对淤泥海滩演变进行随机模拟,研究区域位于江苏连云港海峡西口外淤泥海滩。 一、方差分析 近年来,随着连云港港口的大规模扩建,需要处理开挖及疏浚泥土日增。例如,自1983年起。
The nonlinear time series analysis method is used in this paper to simulate the muddy beach process (1982-1987) in Lianyungang harbour, Jiangsu Province. Through the variance analysis, the influence on the beach process of dumping dredged materials is estimated. The result shows that annual change of dump amount was the first main factor and the distance was the second main factor for the erosion and siltation of that beach. Furthermore, the threshold auto-regressive model of the muddy beach process is established. The prediction of the beach evolution is that, except for the beach part of 1 meter water depth which will undergo a slight erosive process, this beach tends to be in an accumulative process.
