摘　　要：《疏浚与吹填工程施工规范》中泥驳数量计算公式具有局限性,疏浚工程中性能参数不同的泥驳采用不同配置和装驳顺序,会对主船的时间利用率和泥驳等待时间产生不同影响。通过引入泥驳系统运行网络线路图和横道图的概念,在此基础上建立泥驳系统运行数学模型,引入主船累积停滞时间和泥驳累积停滞时间评价指标,提出主船单面或双面靠驳的泥驳配置及装驳方案优化方法,通过实例对模型和优化方法进行验证。结果表明,对既定泥驳船队实现了泥驳装驳顺序优化;对拟组建的泥驳系统,实现泥驳最佳配置方案和初始装驳顺序优化。The calculation formula for the number of mud barges in Construction Code for Dredging and Reclamation Works has limitations.Different mud barges with different performance parameters and loading sequences in dredging engineering have different impacts on the time availability of the main ship and the waiting time of the mud barges.We introduce the concepts of the operation network circuit diagram and bar chart of the mud barge system,and establish a mathematical model for the operation of the mud barge system on this basis.We introduce the evaluation indicators of the accumulated dead time of the main ship and the accumulated dead time of the mud barge,propose an optimization method for the mud barge configuration and loading plan of the main ship with one or two sides berthing,and verify the model and optimization method through examples.The results show that the optimization of the mud barge loading sequence is achieved for the established mud barge fleet.For the proposed mud barge system,the optimal configuration plan and initial loading sequence optimization of the mud barge are achieved.
