摘　　要：针对南通港小庙洪上延航道工程一阶段施工项目的超长排距工况条件,通过对船舶和管线的泥浆扬程、输送阻力损失等水力特性进行分析,验证“新海鲛”与“航绞接1号”采用“2泵+2泵”串联施工工艺能保证此次超长排距施工需求,并推导“航绞接1号”的最佳施工位置,解决绞吸船多级泥泵串联后局部排出压力过高的问题,并将工艺测算结果和优化措施应用于工程实际。结果表明,优化后提高了船组的时间利用率和生产率,取得了较好的施工效果。According to the working condition of super long spacing in the first stage construction project of Xiaomiaohong waterway extension project in Nantong Port,we analyze the the hydraulic characteristics of the ship and pipeline,such as the pressure head of mud pump,transmission resistance loss and etc,verify that the“2 pumps+2 pumps”series construction technology adopted by the“Xinhaijiao”and“Hangjiaojie No.1”can ensure the construction demand of the super long spacing,and deduce the optimal construction position of“Hangjiaojie No.1”,which can solve the problem that the local discharge pressure is too high after the multi-stage mud pump series connection.We apply the results of process calculation and optimization measures to the follow-up engineering practice.The results show that the optimization improves the hourly interest rate and production rate of ship group,and achieves good construction effect.
