针对北仑港港口航道泥沙处理问题,分析了北仑港港口的泥沙特性,提出了不同的泥沙处理方案,分析了各方案的优缺点,并引入PCA(主成分分析法)-熵权系数评价模型对不同方案进行评价和优选。结果表明,PCA-熵权系数评价模型避免了同类型指标数过多所造成的权重分配不合理问题,具有较好的应用和推广价值;方案6经济可行、技术先进、泥沙资源利用率高,宜作为北仑港港口泥沙处理的主要方案。
According to the problem of sediment handling in Beilun Harbor, the sediment characteristics of Beilun Port are analyzed, and different sediment disposal schemes are proposed. The advantages and disadvantages of each scheme are analyzed. PCA (principal component analysis) - entropy coefficient Evaluation model to evaluate and optimize different programs. The results show that the PCA-entropy coefficient evaluation model avoids the problem of irrational weight distribution caused by too many indicators of the same type and has good application and popularization value. The scheme 6 is economically feasible, advanced in technology and has high utilization rate of sediment resources , Should be used as Beilun port silt handling the main program.
