The invention discloses a method for measuring post-earthquake railway structure deformation characteristics by adopting an accurate measurement network system. Under the influence of earthquakes and the like, control points of different grades in railway construction are displaced or damaged. According to the method, control network coordinates of different levels are dynamically updated level by level, multidirectional spatial deformation characteristics of a railway are analyzed based on remeasured accurate measurement network control results of different levels, and assessment of the usability of the track structure affected by the earthquake is completed by combining overall and local transverse and longitudinal deformation values of the track. According to the method, the original control result is utilized to the greatest extent, smooth connection of the track coordinate system is guaranteed, and a data reference is provided for engineering involution.

    本发明公开了一种采用精测网体系测量震后铁路构筑物变形特征的方法。受地震等影响,铁路建设中的不同等级控制点存在位移或损坏。本发明对不同级别的控制网坐标进行逐级动态更新,基于复测的不同级别精测网控制成果,对铁路的多方位空间变形特征进行了分析,结合轨道整体及局部的横向、纵向变形量值,完成了受地震影响轨道结构可利用性评估。本发明最大程度的利用了原有控制成果,且保障了轨道坐标系统的平顺衔接,为工程复旧提供了数据基准。
