Zusammenfassung:	Provided is a foundation pit deformation measuring device and method thereof. The foundation pit deformation measuring device comprises a steel wire, a spring, a tilt angle sensor, a displacement sensor, an upper fixing plate and a lower fixing plate, wherein the upper fixing plate is fixed to the upper edge of the side wall of a foundation pit and is perpendicular to the side wall of the foundation pit, the bottom end of the steel wire is fixed to the bottom close to the side wall of the foundation pit, the lower fixing plate is fixed to the top of the steel wire and is perpendicular to the steel wire, one end of the spring and one end of the displacement sensor are connected with the upper surface of the lower fixing plate, and the other end of the spring and the other end of the displacement sensor are connected with the lower surface of the upper fixing plate. The elastic coefficient of the spring is 1-2N/mm. The tilt angle sensor is fixed to the top end of the steel wire, is perpendicular to the steel wi
