摘要
海光缆的敷设质量直接决定海光缆系统的使用寿命。介绍海光缆深水定余量敷设与浅海定张力敷设的区别,比较两种控制模型的适用性,同时简要介绍相对成熟的定余量敷设直线模型及其应用,并在此基础上分析直线模型的局限性,提出了基于悬链线的深水敷设模型。其中,重点分析了下坡敷设的情况,得出了此地形条件下敷设海光缆长度与船只行驶距离的关系,即布缆速度与船速的关系。这将对深海布缆控制提供参考。
The quality of sea cable laying directly determines the service life of the optical cable system.The article introduces the differences and compare the applicabilities between the undersea fiber cable fixed- slack deployment in the deep sea and fixed-tension deployment in the shallow sea.And the paper briefly introduces the relatively t^ature liner model of fixed-slack deployment and its applications.According to the analysis of the limitation of the liner model,the deep-sea fiber cable laying model based on the catenary has been proposed.There is a selective analysis in the situation of the deployment on the downhill and the relationship of the length of the undersea fiber cable paid out and the distance of ship＇s moving,namely the relatiobship of the speed of the cable deployed and the speed of the ship.The research has a guiding significance for the control of deep-sea fiber cable deploment.
