摘　　要：为掌握采矿过程中对临近武九铁路线某段路基的变形影响程度,针对铁路沿线地形复杂、无法通视、无供电及网络等条件,采用全自动监测预警系统,对武九线某段路基的稳定状态进行远程连续监测,并建立预警及信息管理系统。全套系统运用传感技术、数据采集与传输技术和信息管理技术。通过一段时间的运行应用,该系统能实时掌握该段铁路路基变形状态,出现险情也可第一时间预警,达到保障铁路运营安全的目的。In view of the severe conditions along the railway of complex terrain, lack of intervisibility, no power supply and no internet access, the automatic monitoring and warning system will be used to acquire the deformation degree of a certain subgrade influenced by mining near the railway line from Wuhan to Jiujiang. The system is to monitor the stability of the subgrade in a continuous way to establish an early-warning and information management system. By conducting the sensor technology, data collecting technology and information management technology, the system will acquire the deformation degree in real time, and send early-warning signal at the very first moment as any danger incurs, thus to ensure the safety of railway operation.
