摘要
利用2008年5月12日汶川8.0级地震发生时三峡井网8口井孔的水位阶变资料,采用承压井潮汐理论反演水井含水层体应变固体潮系数的方法,估算出该地震引起的三峡坝区、库首区应力场的调整变化。
On the basis of analysis of the change of water level on may 12,2008 from the 8 wells in the Three Gorge well network, a method for inverting the parameters of the strain tide effect according to the tide theory of the pressure well is adopted. The adjustments of the stress field at the dam site and the head of the Three Gorge reservoir area are cauculated.
