    • PROBLEM TO BE SOLVED: To provide an underground displacement measuring apparatus capable of measuring displacement of underground soil without being restricted by a measurement range.SOLUTION: An underground displacement measuring apparatus 101 includes a plurality of sensor devices 101a arranged so as to be mutually separated at intervals in a bore hole 3. Each sensor device 101a includes an ultrasonic transmitter 11 for transmitting an ultrasonic wave, an ultrasonic receiver 12 for detecting the ultrasonic wave and a controller 20. The controller 20 in the sensor device 101a acts as propagation time detection means for detecting propagation time required from transmission of an ultrasonic wave from the ultrasonic transmitter 11 of the other sensor device 101a up to detection of the ultrasonic wave by the ultrasonic receiver 12 of the sensor device 101a itself between the sensor device 101a itself and the other sensor device 101a, and acts as displacement calculation means for calculating displacement of the sensor device 101a itself from the other sensor device 101a based on the detected ultrasonic propagation time and ultrasonic propagation velocity.

    • PROBLEM TO BE SOLVED: To provide a position measuring system correcting position information accurately with a simple facility constitution.
      SOLUTION: In this position measuring system 1, a moving body 2 is loaded with a displacement sensor 34 for measuring displacement of a rail, a range finder 31 for measuring a position, and a data processing device 4. The data processing device 4 in the position measuring system 1 includes a rail joint gap position management DB 43 having position information of each rail joint gap 9 registered therein. A control part 41 of the data processing device 4 monitors measurement data of the displacement sensor 34 and measurement position data of the range finder 31. The control part 41 extracts measurement position data when the measurement data of the displacement sensor 34 show characteristic data which are peculiar to the rail joint gap 9, or rail joint gap position information existing in the periphery thereof from the rail joint gap position management DB 43, and holds it as a prediction value. Then, the control part 41 collates measurement position data by the range finder 31 with the extracted prediction value, and corrects the measured distance to the prediction value (registered rail joint gap position information) in the case of disagreement.
