| 摘 要： | 基于北京五里营井观测资料,分析了汶川Ms8.0和日本Ms9.0地震前后的水位、水温变化,发现两次地震前后北京五里营井水位、水温的变化为震前上升、震后恢复,两次地震前后变化基本一致,不受地震方位和震中距离的影响.这种变化可能是井孔区域受地震波的作用,岩石中裂缝系统出现弹一塑性的张开和闭合,而张开程度小于闭合程度,岩石的孔隙度减少,含水层被压缩,致使井水位出现明显的抬升；而地下较热的水上涌是导致水温突升的主要原因.

| Abstract: | On the basis of observations of Wuliying Well,we studied the coseismic effects of water level and temperature and found both of the data raised by Wenchuan and Japan earthquakes independent with the focal mechanism or seismic location.Through the primary analysis,we found that the rock fracture shown the elastic-plastic spread and shutting by the influence of the quakes on the well round area.The decreased rock porosity and the pressed water-bearing stratum made the water level rise,the up deep warmer water made the temperature go up. |
