SPECIFIC RESISTANCE MEASURING DEVICE, MANAGEMENT METHOD FOR GROUND IMPROVEMENT METHOD, AND SPECIFIC RESISTANCE MEASURING METHOD
To improve accuracy of specific resistance measurement in the ground.SOLUTION: In a specific resistance measuring device 1A, a capacitor electrode device 10A has a pair of capacitor electrodes 10 composed of dielectric bodies 13 opposite to a porous wall W of a hole H in a ground E and conductors 14 connected to the dielectric bodies 13 as a pair of current electrodes 11 arranged in an extension direction of the hole H, has the pair of capacitor electrodes 10 as a pair of potential electrodes 12 arranged in the extension direction of the hole H while causing AC current to flow into the ground E by applying an AC voltage between the pair of current electrodes 11, and measures a potential between the pair of potential electrodes 12. A measuring part 20 measures specific resistance in the ground E by a potential between the AC current flowing into the ground E by the current electrodes 11, and the potential electrodes 12 measured by the potential electrodes 12. The current electrodes 11 and the potential electrodes 12 can be measured by only approaching the pore wall W, which measures the specific resistance in the ground E while reducing the influence of irregularity of the porous wall W and can improve accuracy of specific resistance measurement of the ground E.SELECTED DRAWING: Figure 2
【課題】地中の比抵抗測定の精度を向上させる。【解決手段】比抵抗測定装置１Ａでは、キャパシタ電極装置１０Ａは、地中Ｅの孔Ｈの孔壁Ｗに対向する誘電体１３と誘電体１３に接続される導電体１４とからなるキャパシタ電極１０の一対を一対の電流電極１１として孔Ｈの延在方向に沿って配置し、一対の電流電極１１の間に交流電圧を印加することにより地中Ｅに交流電流を流しつつ、キャパシタ電極１０の一対を一対の電位電極１２として孔Ｈの延在方向に沿って配置し、一対の電位電極１２の間の電位を測定する。測定部２０は、電流電極１１により地中Ｅに流された交流電流と、電位電極１２により測定された電位電極１２の間の電位とにより、地中Ｅの比抵抗を測定する。電流電極１１と電位電極１２とは、孔壁Ｗに近接させられるだけで測定が可能であるため、孔壁Ｗの凹凸等の影響を低減させつつ地中Ｅの比抵抗を測定し、地中Ｅの比抵抗測定の精度を向上できる。【選択図】図２
