摘要

    摘要
  • 摘要: 以Hsieh模型为基础，提出了利用地震前后承压井水位潮汐分波的振幅及初始相位变化与否作为判断依据，检验井水位对含水层潮汐应力响应是否满足不排水条件的简便方法. 将该判别方法用于分析会理川-06井和川-18井水位观测数据， 利用Baytap-G潮汐分析方法分别计算出3次选定地震前后两井水位各分波（M2和O1）振幅和相位值. 结果表明，川-06井水位潮汐响应先满足排水条件，其后地震波增强含水层导水（渗透）性使其满足不排水条件；川-18井由于导水系数较大，水位潮汐响应满足不排水条件．最后，结合理论潮汐应力潮汐分析结果，通过理论模型反推出震前和震后川-06井所揭露含水层的导水系数和Skempton系数，以及川-18井所揭露含水层的Skempton系数．
    Abstract: Based on the Hsieh model, a novel but simple method is proposed to examine whether the undrained condition is satisfied for the response of well water-level to tidal stress action, by monitoring the change of amplitude and initial phase of tidal constituents of the water-level.Water-levels of the well C(Chuan)-18 and C-06 are analyzed with the examination method. The chosen amplitude and initial phase of tidal constituents (M2 and O1) of the water-level in C(Chuan)-18 and C-06 well, and theoretical tidal stress before and after the earthquakes, are calculated with the Baytap-G tidal analysis method. The result shows that the tidal response of the water-level in C-06 well was drained at first, then it was in an undrainedstate because seismic waves enhanced the aquifer hydraulic conductivity (permeability). Due to high hydraulic conductivity, the tidal response of the water-level in C-18 well meets undrained state. Finally, we figure out the Skempton coefficient and the Transmissivity of the aquifer tapped by the C-06 well, as well as the Skempton coefficient of the aquifer tapped by the C-18 well.
