CPⅢ点位变化对轨道线形的影响

Effect of CPⅢ Point Position Change on Track Alignment

为了更好地解决高速铁路运营监测中重点监测段落划分及沉降监测等问题,以本次复测和竣工复测的CPⅢ实测数据为基础,通过轨道监测软件分析CPⅢ点位横向、垂向变化对轨道线形的影响,沉降量最大值为-44.0mm与工务段提供的重点沉降监测数据一致;经过对不同段落的对比分析,分析结果与实测数据吻合性较高,验证了方法的可靠性,较好地解决了重点段监测划分及沉降监测问题。

In order to better solve the problems of key monitoring section division and settlement monitoring in high-speed railway operation monitoring,the monitoring problem of key settlement sections is analyzed by using the influence of CPⅢ point change on the alignment of the orbit. Based on the CPⅢ measured data of this retest and completion retest,the lateral and vertical changes of CPⅢ points and influence on track alignment thereof are analyzed by the orbit monitoring software. The maximum settlement amount is - 44. 0 mm,which is consistent with the key settlement monitoring data provided by the engineering section. After comparing and analyzing the different sections,the analysis results are in good agreement with the measured data,which verifies the reliability of the method. That is to say,the problem of monitoring division and settlement monitoring of key sections can be solved well.
