Abstract

地盤・岩盤の変形と地下水流動の連成理論である多孔質弾性論を概説し,気圧変動や地球潮汐に伴う井戸水位,間隙水圧の応答が,地盤・岩盤の変形と地下水流動の連成現象として定量的に記述できることを示した.次に,気圧変動,地球潮汐に伴う井戸水位,間隙水圧の応答から,水理特性を評価する方法を整理し,気圧変動における不飽和帯の影響や井戸貯留の影響などの課題,留意点などをまとめた.最後に,気圧変動,地球潮汐に伴う井戸水位,間隙水圧の応答を利用することによって期待される今後の水理特性の評価の可能性について考察した.

The theory of poroelasticity whi c h describes the coupled behavior between mechanical deformation and fluid flow is overviewed. We summarized that the responses of pore pressure and water level in wells to atmospheric loading and earth tides were formulated with this theory. In order to estimate hydraulic properties of the formations from field data, the effects of the unsaturated zone process and wellbore storage on the amplitude attenuation and phase lag of the measured data relative to the loading were discussed. Finally, we tried to show the possibilities of new methods to determine hydraulic properties through the responses of pore pressure or water level to atmospheric loading and earth tides.
