摘　　要：为保证高铁线路的平顺性,需对运营期高速铁路重点变形地段进行周期性沉降监测。高速铁路重点地段沉降监测具有监测点数量多、数据量大、周期性、长期性监测等特点。针对以上特点,本文利用C#语言调用Spire.XLS组件生成重点地段沉降监测数据纵断面沉降曲线图及上下行沉降趋势合成图等,对多期观测成果可视化输出。最后结合某高速铁路重点地段沉降监测数据实例,直观地展示了重点地段沉降变形量及变形趋势,为后期沉降数据分析及设备管理单位维修、养护线路提供数据参考。In order to ensure the smoothness of high-speed railway lines,periodic settlement monitoring should be carried out on key deformation sections of high-speed railway during operation.The settlement monitoring in key sections of high-speed railway is char-acterized by large number of monitoring points,large amount of data,periodic and long-term monitoring.In view of the above charac-teristics,this paper uses the C#language to call Spire.XLS component to generate longitudinal section settlement curve and upstream and downstream settlement trend synthesis map of settlement monitoring data in key sections,so as to visualize the output of multi-pe-riod observation results.Finally,combining with the settlement monitoring data example of a key section of high-speed railway,the settlement deformation amount and deformation trend of the key section are visually displayed,which provides data reference for later settlement data analysis and equipment management unit to repair and maintain the lines.
