英文摘要	将含水层看成孔隙弹性介质,建立二维承压含水层理想模型,计算周围应力场变化引起的井水位变化的分布和量级,讨论井水位突变的消散规律.根据消散过程,用反褶积的方法,从井水位数据计算周围应力应变场的变化,并用数值方法和会理川06井的固体潮数据验证这种方法的可行性.应用数值模拟结果探讨同震井水位阶变的机制,认为简单的孔隙弹性模型不能解释同震井水位变化特征.; The aquifer can be treated as poroelastic media in current research. An ideal 2D confined aquifer model was founded to calculate the response of the groundwater level to the variation of stress field. Then the dissipation law of abnormity of groundwater level was discussed. A deconvolution method to invert stress-strain field from groundwater level data when considering the dissipation process was also discussed. Results from forward calculation and earth tide data of Huili Chuan-06 well were analyzed to confirm the deconvolution method. At last, the mechanism of co-seismic step variation in groundwater level was analyzed. It was concluded that a simple poroelastic model cannot explain the amplitude of variation.; 国家自然科学基金; 4; 683-691; 53
