The invention belongs to the technical field of gauge detection, and provides a railway gauge detection method, which comprises the following steps of: 1, establishing a permanent coordinate system, establishing a long-term stable station gridding precision control network at a station, and providing a spatial three-dimensional coordinate starting reference for daily operation and maintenance of the station; 2, establishing three-dimensional space monitoring data by using a total station on the basis of a station control coordinate system; 3, placing an auxiliary prism matched with the total station at a fixed position, and ensuring that the position is unique and unchanged each time; and step 4, periodically measuring the railway platform measuring point, comparing data changes, and judging whether the railway gauge is displaced or not. According to the invention, aiming at large-scale passenger stations and complex-form house building equipment, direct or indirect monitoring station displacement changes are respectively studied, and the displacement change quantity of the station is accurately positioned and analyzed.
本发明属于限界检测技术领域,提供了一种铁路限界检测方法,包括如下步骤:第一步,建立永久性坐标体系,在车站建立长期稳定的车站网格化精密控制网,为车站日常运营维护提供空间三维坐标起算基准;第二步,在车站控制坐标体系的基准上,使用全站仪建立三维空间监测数据;第三步,将与所述全站仪匹配的辅助棱镜放置在固定位置上,确保每次位置唯一不变;第四步,对铁路站台测量点位进行周期测量,对比数据变化,判定铁路限界是否发生位移。本发明针对大型客站、形式复杂的房建设备,分别研究直接或间接监测站台位移变化的方法,精确定位分析站台的位移变化量。
