大型耙吸船与自航泥驳联合施工的工效分析

吹填造陆项目需要从远距离取砂到近岸填陆,自航泥驳船联合耙吸挖泥船施工工艺能提高远运距项目综合工效,补充耙吸船施工能力不足,从而降低综合成本。根据施工工艺特点,基于影响因素分析,建立不同工效计算理论模型,借助实际施工效率数据,测算不同运距、不同工艺形式的综合工效,得到典型工况的综合效率及应用边界条件,为工程应用耙吸船与自航泥驳船联合施工方案提供数据支持和决策参考。

Efficiency analysis on joint construction of large trailing suction hopperand self-propelled hopper barge

Reclamation project needs to take sand to the shore from long distance.Joint construction with the hopper dredger dredging and hopper barge can improve the efficiency of the project from the far distance,also can supplement the construction capacity and reduce the overall cost.We establish an effective calculation method by the process feature and factor analysis method.With the actual construction data,we calculate different forms of comprehensive efficiency from the different transport distance.We obtain the combined efficiency of the typical working conditions and applied boundary conditions,which can provide the data for support and decision.
