三峡库区深水航道航标配置分析

Research of configuration for buoys in deep channel of the Three Gorges Reservoir area

三峡库区175 m蓄水运行后,由于水深增加,河道变宽,风浪作用增强,先前在水上设置的浮标变成了深水标,原有的航标浮具(标志船、标体、标灯)配置不能适应航道条件变化,存在着整体稳定性变差、助航效果降低、安全隐患增大等诸多问题。文章结合目前三峡库区航标设置及系留设施有关情况,通过浮具的受力分析与维护实践,对航标的浮具、系缆设施、钢缆、锚石形状、尺寸等进行了匹配选型,找到了库区深水航标合理的型号配置。

After the running of the water storage of the Three Gorges Reservoir at 175 m, the environment of traditional navigation aids is changed into deep water. Original buoy（flag ship, beacon body, beacon light）configura- tion can not adapt to changes in channel conditions. There exist a lot of problems including the deterioration of over- all stability, the reduction of navigational aids effect and the increasing security risks. In this paper, combined with the current settings and the situation of the Three Gorges Reservoir buoy mooring facility, the floating buoy, mooring facilities, ropes, shape and size of anchor stone were selected on the basis of stress analysis and maintenance of buoying device, and the reasonable model configuration was obtained.
