摘要:
［目的］目前，轨道静态几何尺寸偏差的测量主要采用轨距尺、弦线和轨道检测小车等方法，这些方法虽能较准确地评估线路质量，但在铁路立交工程施工中无法实现快速、实时的监测。因此，有必要对轨道静态几何尺寸偏差的自动化监测精度开展研究。［方法］由此研制了铁路立交工程自动化监测系统，该系统由互联网、数据库、自动化监测等多种技术融合而成，可实现全天候实时监测。为验证其监测精度，在自动化监测同时，采用水准测量、轨距尺测量、弦线法等人工监测方法进行了验证，将人工监测的数据与自动化监测的数据进行对比分析。［结果及结论］自动化监测在铁路轨道几何状态监测的精度高，可满足现场施工条件对测量精度的要求。

［Objective］ Currently, the measurement of track static geometric dimension deviations primarily employs methods such as track gauges, chord lines, and hand-push rail inspection trolleys. Although these methods can relatively evaluate track quality accurately, they are incapable of rapid and real-time monitoring during railway interchange construction. Therefore, it is necessary to conduct a research on the accuracy of automatic monitoring for track static geometric dimension deviations. ［Method］ As a result, an automatic monitoring system for railway interchange project is developed. The system is a combination of multiple technologies such as Internet, database, and automatic monitoring, and can realize real-time monitoring around the clock. To verify its monitoring accuracy, while conducting automated monitoring, manual monitoring methods such as level measurement, gauge measurement, and chord method are simultaneously used for validation. Data of manual and automatic monitoring are compared and analyzed. ［Result & Conclusion］ Automatic monitoring shows a high accuracy in monitoring railway track geometric status, satisfying the measurement accuracy requirements for site construction conditions.
