鐵路地表變形自動(dòng)監(jiān)測技術(shù)及其工程應(yīng)用
摘 要：為掌握采礦過程中對(duì)臨近武九鐵路線某段路基的變形影響程度，針對(duì)鐵路沿線地形復(fù)雜、無法通視、無供電及網(wǎng)絡(luò)等條件，采用全自動(dòng)監(jiān)測預(yù)警系統(tǒng)，對(duì)武九線某段路基的穩(wěn)定狀態(tài)進(jìn)行遠(yuǎn)程連續(xù)監(jiān)測，并建立預(yù)警及信息管理系統(tǒng)。全套系統(tǒng)運(yùn)用傳感技術(shù)、數(shù)據(jù)采集與傳輸技術(shù)和信息管理技術(shù)。通過一段時(shí)間的運(yùn)行應(yīng)用，該系統(tǒng)能實(shí)時(shí)掌握該段鐵路路基變形狀態(tài)，出現(xiàn)險(xiǎn)情也可第一時(shí)間預(yù)警，達(dá)到保障鐵路運(yùn)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
