| 摘 要： | 对山西、河北、北京和江苏地区14口观测井的前驱波记录次数进行了统计分析，并给出了前驱波记录次数占统计年份地震总次数的百分比；利用Cooper等人推导的井-含水层系统放大因子表达式，分析了井-含水层系统的特征参数与前驱波响应能力之间的关系. 研究结果表明，井-含水层系统对前驱波的响应能力大小与含水层的固有周期存在一定关系,即固有周期越大，记录前驱波的能力越强； 井-含水层系统对前驱波的响应能力大小还与导水系数和井孔半径平方的比值大小有关，该比值越大，响应能力越强.

| Abstract: | Recording number of precursors from fourteen observation wells in Shanxi, Hebei, Beijing and Jiangsu region is analyzed and percentage of recording number of precursors to total number of earthquakes during the statistic years is presented. The relationship between characteristic parameters of well-aquifer system and responding ability to precursors is analyzed by the expression of amplification factor of well-aquifer system induced by Cooper et al. The results indicate that responding ability of well-aquifer system to precursors is related to inherent period of well-aquifer, that is to say, the greater the inherent period is, the stronger the ability of recording precursor is. Responding ability of well-aquifer system to precursors is also related to ratio of transmissibility coefficient to square of radius of wells, and the greater the ratio is, the stronger the responding ability is. |
