摘要
本文给出了利用井水位的固定潮效应反演含水层应力变化的新方法。通过菏泽地震深井水位的变化,估算了鲁西应力场的调整变化。其中豫01井在这次地震中应力调整变化最大,达—1160hPa。利用井水位的固体潮效应反演含水层应力变化,比利用气压效应更接近实际情况。
In this paper, a new method of stress variation in an aquifer inversed by the tidal effect of the water level in a deep well is given. The adjustment of the stress field in the west of Shandong province is estimated by the variation of the water level in deep wells during and after the Heze earthquake. The adjustment of the stress in the well Yu-01 in the earthquake is the biggest and reaches -1160 hPa. The variation of stress in the aquifer inversed is closer to practice by the tidal effect of the water level in a deep well than by the barometric effect.
