自航式耙吸挖泥船疏浚性能评估系统设计*

目前耙吸挖泥船疏浚效果的评价主要依靠施工人员的常识经验，例如以牺牲大量的施工时间来换取泥沙产量的最大化，反而造成单土方成本较高。结合耙吸挖泥船厦门港实测施工数据，构建多指标疏浚性能评价体系，各性能指标的权值采用熵值法进行确定。研究表明：多指标评估体系能够更加全面、客观地反映耙吸挖泥船疏浚性能，且与挖泥船辅助决策系统的测试结果保持一致。

Design of dredging performance evaluation system for the trailing suction dredger

At present, the evaluation of the dredging effect of the drag suction dredger mainly relies on the common sense experience of the construction personnel, such as sacrificing a large amount of construction time in exchange for maximizing the yield of sand, but it causes a higher cost of single earthwork.Combined with the measured construction data of the trailing suction dredger in Xiamen Port, a multi-index dredging performance evaluation system is constructed, and the weight of each performance index is determined using the entropy method.The research shows that the multi-index evaluation system can more comprehensively and objectively reflect the dredging performance of the drag suction dredger, and it is consistent with the test results of the auxiliary decision-making system of the dredger.
