| 講演要旨(和文) | | ライフライン等の建設にあたり,過去に投棄・埋め立てされた人工地盤に遭遇することはしばしば起こることである.これらの埋立範囲や埋立量を非破壊で見積もる手段として,省力型三次元比抵抗探査を試みた.その結果,人工地層内でコンクリート片などが多量に含むゾーンが,比抵抗の分布にあらわれた.しかし,人工地層とその下位に分布する地山との境界は,比抵抗プロファイルでは判別不可能であった. |

| | 講演要旨(英文) | | We conducted a labor saving three-dimensional 3-D resistivty survey on surplus soil deposits from constructions. Rsesistivity profiles were interpreted by the borehole and electrical logging data. As a result, the profiles reflect the variation of facies in the deposit. In contrast to this, the boundary between the deposit and the lower layer is not clear. There is a large possibility that the 3-D resistivity survey is a useful method for a complex structure such as landfills. |
