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
