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(wǎng)絡等條件，采用全自動監(jiān)測預警系統(tǒng)，對武九線某段路基的穩(wěn)定狀態(tài)進行遠程連續(xù)監(jiān)測，并建立預警及信息管理系統(tǒng)。全套系統(tǒng)運用傳感技術、數(shù)據(jù)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(tǒng)能實時掌握該段鐵路路基變形狀態(tài)，出現(xiàn)險情也可第一時間預警，達到保障鐵路運營安全的目的。
關鍵詞：變形監(jiān)測技術；全自動監(jiān)測預警系統(tǒng)；自動采集；無線傳輸；鐵路路基沉降

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
