摘要： PROBLEM TO BE SOLVED: To provide an elastic wave probe system capable of detecting a discontinuous surface precisely, while eliminating layout restrictions and improving the degree of freedom in probing. SOLUTION: A vibration detection section 5a of a geophone 5 acquires reflection waves RW by elastic waves EW and a vibration value by direct waves within a prescribed amount of time ranging from acquisition start time t0 to t4 based on reference time t1 synchronized to the occurrence time of the elastic waves EW by a built-in timer 5c. Therefore, regardless of radio connection of the geophone 5 to a trigger hammer 3 and a radio transceiver 7, the reference time managed by the geophone 5 is synchronized with the occurrence time of elastic waves by the trigger hammer 3, and an analysis computer 9 can perform a geological analysis by precise vibration value data without any deviation between both the times. Further, since the geophone 5 is connected to the trigger hammer 3 by radio, the geophone can be arranged at a desirable position for a geographical analysis. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method of searching a front of a tunnel working face, generating an S wave by a method less influencing the surroundings without destroying a ground. SOLUTION: A shield machine 1 comprises a cutter face 7 and a skin plate 9. Parts 3 to oscillate and parts to be oscillated 5 are alternately disposed on the cutter face 7. The parts 3 and the parts 5 project from the shield machine 1 to a tunnel front working face. Each part 3 comprises a pipe 22 and an oscillator 13 press-fitted to the inside of the pipe 22. The S wave is non-destructively generated by the parts 3 when the oscillator 13 having a super magnetostrictive element 27 oscillates. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method of surely oscillating an S wave inside any one of the ground surface or a boring hole. SOLUTION: An oscillator 1 with a pressure-fit part 5, mounted on a rod 9 projected from a vibrator 3, is put in the boring hole 23 and the oscillator 1 is moved to a predetermined position. A movable arm 7 of the pressure-fit part 5 is then extended, and the oscillator 1 is fixed inside the boring hole 23. The vibrator 3 is vibrated, to rub the pressure-fit part 5 against a wall of the boring hole 23, thus generating the S wave. The oscillator 1 is constituted, such that the rod 9 can be reciprocated by a super-magnetostrictive element 15. COPYRIGHT: (C)2009,JPO&INPIT
