鐵路地表變形自動監測技術及其工程應用
摘 要：為掌握采礦過程中對臨近武九鐵路線某段路基的變形影響程度，針對鐵路沿線地形復雜、無法通視、無供電及網絡等條件，采用全自動監測預警系統，對武九線某段路基的穩定狀態進行遠程連續監測，并建立預警及信息管理系統。全套系統運用傳感技術、數據采集與傳輸技術和信息管理技術。通過一段時間的運行應用，該系統能實時掌握該段鐵路路基變形狀態，出現險情也可第一時間預警，達到保障鐵路運營安全的目的。

Abstract: 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.
Key words: deformation monitoring technology； automatic monitoring and early-warning system；automatic collection； wireless transmission； subgrade settlement of railway
