To provide a ground investigation method that can perform a ground investigation easily and reliably and that can reliably bear support piles using a bearing ground.SOLUTION: The ground investigation method is configured to include an excavation step and an investigation step. The excavation step is a step for excavating an excavated hole 2 in a ground G by a predetermined depth. The investigation step is a step for inserting, into the excavated hole 2, a radar transceiver 6 that is provided on the lower end of a rotary member 4 so as to deviate from the rotary axis center of the rotary member 4 outwards in a radial direction, the radar transceiver 6 transmitting radio waves toward the bottom of the excavated hole 2 and receiving the reflected waves; and afterward rotating the rotary member 4 in order to obtain two-dimensional information within the ground G along the depth direction of the excavated hole 2 and the rotational scanning direction of the rotation of the rotary member 4.SELECTED DRAWING: Figure 1
【課題】簡便かつ確実に地盤の調査を行い、支持地盤によって支持杭を確実に支持することが可能な地盤調査方法を提供する。【解決手段】地盤Ｇに所定深さまで掘削穴２を掘削する掘削工程と、掘削穴２に、回転部材４の下端にその回転軸中心から径方向外向きに偏位して設けられ、この掘削穴２の下方に向けてレーダを送信するとともに反射波を受信するレーダ送受信機６を挿入した上で、回転部材４を回転させて、掘削穴２の深さ方向と前記回転の回転走査方向に亘る前記地盤Ｇの内部の２次元情報を得る調査工程と、を備えた地盤調査方法を構成する。【選択図】図１
