ACQUISITION METHOD OF GROUND INFORMATION, AND ACQUISITION DEVICE OF GROUND INFORMATION
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
【課題】水平方向の調査範囲が広い、振動波による地盤情報の取得技術を提供する。【解決手段】地中に設けられた深さ方向に複数段の水平孔２２、２４に、複数の受信器３２Ｒ1、３２Ｒ2、３２Ｒ1-1、３２Ｒ1-2、３２Ｒ1-3、３２Ｒ1-4、３２Ｒ2-1、３２Ｒ2-2、３２Ｒ2-3が配設された受信器アレイ４４Ｒ１〜Ｒ６をそれぞれ配設し、地表に配設した（地上）発振器４０により振動波を発振した時に各受信器アレイ４４Ｒ１〜Ｒ６で受信される振動波を検出し、該受信器アレイ４４Ｒ１〜Ｒ６間の相関係数を計算することで、地中における振動波の速度分布又は減衰率分布を得る。【選択図】図９
