The utility model relates to a device for monitoring displacement in the process of excavating a foundation pit around a railway, which comprises a steel plate for piling and a plurality of strain acquisition devices arranged on the steel plate and used for acquiring land strain data, and the strain acquisition devices are arranged along the length direction of the steel plate at intervals. The strain acquisition device is also connected with an external strain reading device; and the strain reading device is used for reading strain data of the strain acquisition device. The strain acquisition devices are arranged in the length direction of the steel plate at intervals of 20-30 cm, and the strain acquisition devices are located in the center of the steel plate. The device for monitoring displacement in the foundation pit excavation process around the railway is simple in structure, convenient and efficient to use, low in cost and capable of improving displacement monitoring precision and warning possible coll
