| 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片水位观测数据,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...

| 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 b... |
