    • PURPOSE: A system for measuring the pre-displacement of a tunnel face using an optical fiber sensor and an installation method thereof are provided to precisely measure displacement by corresponding to ground subsidence. CONSTITUTION: A system for measuring the pre-displacement of a tunnel face using an optical fiber sensor comprises protective casings, a housing(100), an optical fiber sensor(200), an expansion unit(300), and a controller(400). A measurement hole(30) is formed in the timbering of a tunnel face(20) using a boring machine. The protective casings are inserted along the measurement hole. The housing has an installation space. The optical fiber sensor is installed along the installation space. The expansion unit covers the housing and has an injection space which can be expanded and contracted. The controller calculates the pre-displacement of the tunnel face by receiving a single from the optical fiber sensor.

    • A method for exploring a ground condition ahead of the tunnel face is provided to obtain the ground condition quickly and easily by using a transducer as an acoustic wave source. A rotation movement apparatus includes a source unit(30), a receiver unit(40), a rotating unit(50), and an external case. The source unit generates an acoustic wave and converts an electrical pulse signal into the acoustic wave. The receiver unit receives the acoustic wave and converts the acoustic wave into the electrical signal. The source unit and the receiver unit are connected to a mounting member through coupling members, respectively. The rotating unit includes a worm, a worm wheel, a support mount, and an implementation member. The worm wheel is rotated by the worm. The support mount supports the worm and the worm wheel. The implementation member is mounted on the worm wheel. The source unit, the receiver unit, and the rotating unit are contained in the external case.
