自航式耙吸挖泥船疏浚性能评估系统设计

Design of dredging performance evaluation system for the trailing suction dredger

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。

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.
