摘　　要：本文主要介绍了一种适用于耙吸挖泥船疏浚施工的新型施工工艺,即动态分层定深施工工艺。首先采用敏感性因素分析法对影响疏浚工程扫浅时间的各个因素进行重要性排序,然后逐个分析每个因素对平整度影响的机理,最后根据分析结果构建动态分层定深计算公式,计算得出分阶段施工的不同定深深度。整个工艺通过加强对施工过程中平整度的阶段控制,从而降低乃至消除后期扫浅时间,减少前期抢工程量造成的垄沟,最终减少施工工期,提高项目收益。通过在洋山四期基建项目中的应用,体现出该施工工艺的可行性和优势。This paper mainly introduces a new construction technology suitable for dredging construction of dredging dredger,namely dynamic delamination and depth determination technology.Firstly,sensitivity factor analysis is used to sort the importance of each factor affecting the trimming time of dredging engineering,and then the mechanism of each factor s influence on the smoothness is analyzed one by one.Finally,the calculation formula of dynamic stratified depth determination is constructed according to the analysis results,which can be used to calculate the different depth settings for phased construction.The whole process is to strengthen the stage control of the flatness in the construction process,so as to reduce or even eliminate the late trimming time,reduce the corrugation caused by the early stage of the project,and ultimately reduce the construction period and improve the project income.This paper also shows the feasibility and advantages of this construction technology through its application in Yangshan Phase 4 infrastructure project.
