石济客运专线并行京沪高速铁路桥梁工程沉降自动化监测

随着我国高速铁路网络的逐步完善,越来越多的新建高速铁路或客运专线与既有运营高速铁路并行或立体交叉。临近高速铁路施工,很大程度上会对既有运营高速铁路的沉降变形造成影响,进而影响高速铁路行车安全。文章依托石济客运专线并行京沪高速铁路工程项目,开展了并行100 km长度内,沉降自动化监测范围确定、系统设计、测点布设设计、预警值确定、系统安装调试实施、系统验收与交付运营及监测数据成果分析等工作,系统梳理了高速铁路自动化沉降监测的实施流程和控制因素。确定了合理的自动化监测范围,研究了自动化监测测点的布设方案,应用的自动化、远程化、实时化、可视化监测系统可确保高速铁路的运营安全,采用的系统安装和调试方法可在同类项目中推广使用。

Automatic Settlement Monitoring of Parallel Section of Shijiazhuang-Jinan Passenger Dedicated Line and Beijing-Shanghai High Speed Railway

With the improvement of China's high-speed railway network, more and more new high-speed railways and passenger dedicated lines are in parallel or cross-over with existing high-speed railways. These constructions adjacent to the high-speed railway will dramatically affect the settlement of the existing lines, which will affect the safety of the high-speed railway. Based on the project of Shijiazhuang-Jinan passenger dedicated line parallel with Beijing-Shanghai high-speed railway, the determination of the automatic monitoring range of settlement, system design, measuring point layout design, warning value determination and system installation and testing, system acceptance and hand over and monitoring data analysis etc are carried out within the length of 100km. The system combed the implementation process and key factors of high-speed automatic settlement monitoring. The reasonable automatic monitoring range was determined, and the layout scheme of automatic monitoring measuring points was studied. The automatic, remote, real-time and visual monitoring system can ensure the safety of high-speed railways. The system installation and testing methods can be used in similar projects.
