Suspension bridge main cable strand marking method
The invention relates to a method for marking a main cable strand of a suspension bridge, which comprises the following steps of: tensioning the main cable strand to different stress states, and measuring the main cable strand to calculate an unstressed cable length L0; and the main cable strand is tensioned to be in an empty cable state, and according to the calculation result of the unstressed cable length L0, the bridge structure feature position is marked on the main cable strand through survey lofting. According to the marking method for the main cable strand of the suspension bridge, the existing manufacturing precision of the main cable strand does not need to be improved, namely, the manufacturing cost is not increased. According to the method, the main cable strand is tensioned to different stress states, the main cable strand is measured, the tension elastic elongation and the temperature deformation are corrected, and the unstressed cable length of the main cable strand is obtained; precise marking at the specific length position of the main cable strand is achieved, marking points correspond to bridge structure feature positions one to one, and marking alignment installation can be conveniently carried out during bridge site construction.
本申请涉及一种悬索桥主缆索股标记方法，包括：将主缆索股张拉至不同的受力状态，对主缆索股进行测量，以计算无应力索长L0；将主缆索股张拉至空缆状态，根据无应力索长L0的计算结果，将桥梁结构特征位置通过测量放样标记到主缆索股上。本发明提供一种悬索桥主缆索股标记方法，不需要提高主缆索股既有制造精度，即不增加制造成本。根据本发明内容，将主缆索股张拉至不同的受力状态，对主缆索股进行测量，修正张拉弹性伸长量和温度变形量，得到主缆索股的无应力索长；实现主缆索股特定长度处的精确标记，标记点与桥梁结构特征位置一一对应，便于桥址施工时进行标记对位安装。
