运用高速铁路轨道精密工程测量技术获取运营期地铁轨道几何状态数据并进行轨道几何状态平顺性分析,进而指导运营期地铁轨道精调。地铁轨道精调前后获取的轨道几何状态数据对比表明,采用轨道精密工程测量技术进行地铁运营维护调整,可以大幅度提高轨道的平顺性。
The high-speed railway track precision engineering measurement technology is used to obtain the geometric state data of the subway track during the operation period and to analyze the ride comfort of the track geometry so as to guide the fine adjustment of the subway track during the operation period. Comparison of orbit geometric state data obtained before and after the subway track fine tuning shows that the use of orbit precision engineering measurement technology for subway operation and maintenance adjustment can greatly improve track ride.
