摘要

以孔隙弹性理论和水文地质学原理为基础,给出井水位波动与含水层介质体应变变化关系的数学表达式,结合固体潮理论分析了井—含水层系统水位潮汐波动对体应变固体潮的响应特征,用水位潮汐波来反演含水层体应变的变化,将反演结果与体应变实测资料得到的结果进行对比,发现二者有较好的一致性,说明用水位潮汐波来反演含水层体应变的方法是可行的,它为了解含水层的水文地质特性、体应变的变化及探索地震前兆提供了借鉴。
Based on the linear poroelastic and hydrogeology theory, mathematical express between water level change and aquifer volume strain is given. Combined with earth tidal theory,the authors analyzed the response characteristics from well-aquifer water level change to earth tide of volume strain and gave out the method of volume strain reversion from water level change. Compared the results of version with real observed data, the authors found that there is a good accordance. This suggests that the method of volume strain version from water level change is proper. It will offer a reference for understanding about hydrogeology characteristics, volume strain and searching for precursor anomalies.
