SHEAR WAVE SPEED MEASUREMENT SENSOR AND SHEAR WAVE SPEED MEASUREMENT SYSTEM
To provide a shear wave speed measurement sensor and shear wave speed measurement system which can be easily installed without reducing the rigidity of a ground improvement body.SOLUTION: A shear wave speed measurement system 3 is provided in a ground improvement body 2 which includes a wall body 21 in a lattice shape in the plan view prepared in the ground, and includes an oscillation part 11 which oscillates a shear wave, a reception part 12 which receives the shear wave oscillated from the oscillation part 11, and a bracing 13 which connects the oscillation part 11 and the reception part 12. The speed of the shear wave propagating in the bracing 13 is slower than the speed of the shear wave propagating in the ground improvement body 2. The bracing 13 comprises: a shear wave speed measurement sensor 1 which has the rigidity that does not generate deformation in the time of installation to the ground improvement body 2; a processing unit which is provided on the outside of the ground improvement body 2, measures the shear wave speed and calculates a residual strain on the basis of the measured shear wave speed; and a waveform generation device which is provided on the outside of the ground improvement body 2 and oscillates the shear wave from the oscillation part 11.SELECTED DRAWING: Figure 2
