Rapid measurement method for ballastless track of large-span cable-stayed bridge
The invention relates to the technical field of bridge construction measurement, in particular to a large-span cable-stayed bridge ballastless track rapid measurement method, which comprises the following steps of: obtaining a main beam correction difference value line shape by combining a closure working condition main beam actual line shape with a closure working condition main beam theoretical line shape; on the basis of the main beam correction difference value line shape, a first main beam theoretical line shape obtained after rough adjustment of the track plate and a second main beam theoretical line shape obtained after rough adjustment of the steel rail are completed are corrected, and a first corrected main beam theoretical line shape and a second corrected main beam theoretical line shape are obtained; measuring to obtain a first main beam actual line shape after rough adjustment of the track plate, and mounting the track plate based on the first corrected main beam theoretical line shape; and measuring to obtain a second main beam actual line shape after rough adjustment of the steel rail, and mounting the steel rail based on the second corrected main beam theoretical line shape. The problems that in the prior art, a model needs to be established according to seasonal changes, the load needs to be manually adjusted to enable the bridge deck load to be the same as the theoretical load, procedures are complex, and work efficiency is low are solved.
本发明涉及桥梁施工测量技术领域，具体涉及一种大跨径斜拉桥无砟轨道快速测量方法，该方法通过合龙工况主梁实际线形结合合龙工况主梁理论线形，得到主梁修正差值线形；基于主梁修正差值线形，对轨道板粗调完成后的第一主梁理论线以及钢轨粗调完成后的第二主梁理论线形进行修正，得到第一修正主梁理论线形和第二修正主梁理论线形；测量得到轨道板粗调完成后的第一主梁实际线形，基于第一修正主梁理论线形，对轨道板进行安装；测量得到钢轨粗调完成后的第二主梁实际线形，基于第二修正主梁理论线形，对钢轨进行安装。能够解决现有技术中需要根据季节变化建立模型，需要人为调整荷载使桥面荷载与理论荷载相同，导致工序复杂，工效低的问题。
