摘　　要：在大方量疏浚与吹填工程施工中受限于单个纳泥区容量不足常需要多个纳泥区组合才能满足需要,在东营港十万吨级进港航道疏浚工程中,总计2 092万m^(3)疏浚土计划全部吹填造陆,施工面临纳泥区多而分散且排泥管线距离长、水域繁忙等系列复杂问题,通过分析其中距离航道起点最远的纳泥区,计算排泥管铺设最大长度,确定单船航道施工里程范围并指导排泥管线方案设计,同时为项目其他纳泥区的排泥管线方案设计、航道适挖里程范围确定总结出快速经验计算方法。In the construction of large-volume dredging and reclamation projects,limited by the insufficient capacity of a single dumping area,it often requires a combination of multiple dumping areas to meet the needs.In the 100000-ton approach channel dredging project of Dongying Port,a total of 20.92 millon cubic meters of dredged soil is planned to be filled for land reclamation.The construction is faced with a series of complex problems such as multiple and scattered dumping areas,long distance of discharge pipelines,and busy waters.By analyzing the farthest dumping area from the starting point of the channel,the maximum length of the laying of the discharge pipe was checked,the construction mileage range of the single ship channel was determined and the discharge pipeline scheme design was guided.At the same time,the rapid experience calculation method was summarized for the scheme design of discharge pipeline in other dumping areas of the project and the determination of suitable excavation mileage range of the channel.
