结合长江南京以下12.5 m深水航道一期工程，应用悬链线理论详细分析计算了作业水深35 m、流向角20o、流速2m/s工况下的铺排排体受力情况，并对异步放排移船工艺进行了优化，提出了铺排初次下排排头控制方法，给出了铺排作业中的一次最佳移船长度。将计算理论进行了35 m水深的现场验证，两者吻合。在铺排作业时，可参考悬链线理论应用技术指导施工。

Combining with the first phase of the 12.5 m deepwater channel under the Yangtze River in Nanjing, applying the theory of catenary,this paper analyzes and calculates the geomattress force situation under the operation conditions of 35 m water depth, flow to the Angle of 20oand velocity of 2 m/s, and optimizes the asynchronous rafting of shifting process, puts forward the head of under catenary control method when first arrangement, gives a best ship moving length in the arrangement. The com-puting theory is put into on-site practices by using the 35 m depth water, and the test results coincided well with calculation. When doing the arrangement works,the catenary theory application technology can be referenced to guide the construction.
