SOIL PROPERTY MANAGEMENT DEVICE AND SOIL PROPERTY MANAGEMENT METHOD
To provide a soil property management device and a soil property management method for evaluating properties of soil on a ground while reducing influence of dryness and unevenness of the ground.SOLUTION: A soil property management device 1A of soil E of a ground S compacted in a construction process of earth work includes: a capacitor electrode device 20A which measures a potential between a pair of potential electrodes 22 by bringing a pair of capacitor electrodes 20 as a pair of potential electrodes 21 close to the soil E of the ground S and by bringing the pair of capacitor electrodes 20 as the pair of potential electrodes 22 close to the soil E of the ground S while AC current is flowed through the soil E of the ground S by applying AC voltage between the pair of current electrodes 21; a measurement section 31 which measures electric resistance of the soil E based on the AC current flowed to the soil E by the current electrodes 21 and the potential measured by the potential electrodes 22; and a soil evaluation section 32 which evaluates properties of the soil E of the ground S in which the electric resistance is measured. The capacitor electrodes 20 can be measured only by being brought close to the ground S, and the properties of the soil E of the ground S can be evaluated while reducing influence of dryness and unevenness of the ground S.SELECTED DRAWING: Figure 1
【課題】地面の乾燥及び不陸の影響を低減させつつ地面の土の品質を評価する。【解決手段】土工事の施工過程で締固められた地面Ｓの土Ｅの土質管理装置１Ａでは、キャパシタ電極装置２０Ａで、地面Ｓの土Ｅにキャパシタ電極２０の一対が一対の電流電極２１として地面Ｓの土Ｅに近接させられ、一対の電流電極２１の間に交流電圧を印加することで、地面Ｓの土Ｅに交流電流が流されつつ、地面Ｓの土Ｅにキャパシタ電極２０の一対が一対の電位電極２２として地面Ｓの土Ｅに近接させられ、一対の電位電極２２の間の電位が測定される。測定部３１で、電流電極２１で土Ｅに流された交流電流と、電位電極２２で測定された電位とにより、土Ｅの電気抵抗が測定される。土質評価部３２で、電気抵抗を測定された地面Ｓの土Ｅの品質が評価される。キャパシタ電極２０は、地面Ｓに近接させるだけで測定が可能であり、地面Ｓの乾燥及び不陸の影響を低減させつつ地面Ｓの土Ｅの品質を評価できる。【選択図】図１
