摘要
南昌红谷隧道是我国目前内河最大的隧道工程,浮运过程要经过3座大桥,且航道宽度只有70 m,水流情况复杂,这些都对浮运作业增加了难度。本文在计算沉管浮运中所受水流力的基础上,针对出坞、顺河流浮运和回旋区调头3种不同情况,制定了2种编队方案。根据工程实际需要,设计了浮运监控系统软件结构,采用C#和WFP技术实现了系统。在管节和拖轮上配置了RTK GPS、DGPS和惯导等导航设备,将浮运编队的实时位置信息显示给指挥人员,对管节出坞、过桥和回旋区调头等监控方法进行了详细描述,并实现了远程终端同步实时显示。目前已经完成了南昌红谷隧道多节沉管的浮运,实践表明系统稳定可靠,形象直观,今后可以应用到同类工程中。
Nanehang Honggu Tunnel is a longest inland underwater tunnel in China. The floating transportation of tunnelsegment is difficult. Two tug formation schemes for tunnel segment floating transportation are made for tunnel segment undocking, down-floating and turning based on water resistance calculation results. The tunnel segment floating transportation monitoring system based on C# and WFP technologies is designed. The remote monitoring is realized by setting RTK CPS, DGPS and inertial navigation devices on tunnel segments and tugs. The successful floating transportation of segments of Honggu Tunnel indicates that the monitoring system is reliable and effective.
