Title:
地盤情報の取得方法及び装置
Document Type and Number:
Japanese Patent JP6936751
Kind Code:
B2
Abstract:
To provide an acquisition technology of ground information by oscillatory wave with a wide range of investigation in a horizontal direction.SOLUTION: Receiver arrays 44R1 to R6 in which a plurality of receivers 32R, 32R, 32R, 32R, 32R, 32R, 32R, 32R, 32Rare arranged are respectively arranged in horizontal holes 22, 24 provided underground at multiple stages in a depth direction. When an (aboveground) oscillator 40 arranged on a ground oscillates oscillatory wave, oscillatory wave received by each receiver array 44R1 to R6 are detected and correlation coefficient between the receiver arrays 44R1 to R6 is calculated, to obtain underground velocity distribution or attenuation factor distribution of oscillatory wave.SELECTED DRAWING: Figure 9
