摘　　要：针对传统沉管基床抛石整平船移船定位精度差、效率低的问题,以襄阳市东西轴线道路工程鱼梁洲段项目为依托,采用GPS定位技术和分步阶段性控制策略,设计了一种沉管隧道基床抛石整平船自动移船控制系统,实现了船舶一键自动化移位。实船测试结果显示,该控制系统性能优越,与传统的人工移船相比平均定位精度提高了38%、平均移船时间节省了88%,对该项目提供了技术支撑。Aiming at the problems of poor positioning accuracy and low efficiency of traditional immersed tube bed riprap leveling ship,based on the Yuliangzhou section of the east-west axis road project in Xiangyang City,this paper uses GPS positioning technology and a step-by-step control strategy to design a kind of automatic ship shifting control system for bed riprap leveling vessel of immersed tube tunnel,which realizes the automatic ship shifting with one key.The test results of the actual ship show that the control system has superior performance,improves the average positioning accuracy by 38% and saves the average shifting time by 88% compared with the traditional manual ship shifting,which provides technical support for the project.
