Quick positioning method for main cable of suspension bridge
The invention provides a quick positioning method for a main cable of a suspension bridge, and belongs to the technical field of suspension bridge construction. The method comprises installation and positioning of a carbon fiber reference cable strand and a linear positioning and adjusting method of a general cable strand based on the carbon fiber reference cable strand, one carbon fiber reference cable strand needs to be provided with a measuring prism and a counterweight device, and the general cable strand needs to be provided with a temperature sensor as an auxiliary facility for auxiliary adjustment. The carbon fiber reference cable strand is introduced as a positioning reference line of a common cable strand in the suspension bridge main cable erection process, the influence of temperature change on the reference cable strand shape can be greatly weakened, the temperature limitation is overcome, the common cable strand is adjusted at any time, the main cable shape positioning efficiency is greatly improved, and the cable shape positioning accuracy is improved. And the linear adjustment is more convenient and accurate.
本发明提供了一种悬索桥主缆快速定位方法，属于悬索桥施工技术领域。本方法包括一种碳纤维基准索股的安装定位，以及基于碳纤维基准索股的一般索股线形定位调整方法，其中一种碳纤维基准索股需要安装测量棱镜和配重装置，一般索股需要安装温度传感器作为附属设施辅助调整。本发明引入了一种碳纤维基准索股作为悬索桥主缆架设过程中一般索股的定位基准线，可以大大减弱温度变化对基准索股线形的影响，克服温度限制而在任意时刻进行一般索股的调整，大大加快主缆线形定位效率，使得线形调整更加方便和精确。
