Abstract
The present disclosure discloses a monitoring device for internal deformation and fine particle loss of a railway subgrade, relating to the field of monitoring devices. The monitoring device includes an internal damage monitoring device arranged in a subgrade ballast layer. The internal damage monitoring device is connected to a resistance acquisition instrument through a wire. The resistance acquisition instrument is in wireless connection with a resistance signal receiver. The monitoring device for internal deformation and fine particle loss of a railway subgrade provided by the present disclosure can remotely realize real-time continuous monitoring of the deformation and fine particle loss inside the railway subgrade under a rail transit load, is economical and convenient, and has high practice value.
