摘要: 从丰镇井水位的潮汐效应、地表水体荷载效应与列车荷载效应分别计算出井水位对各类应力-应变的响应灵敏度, 其结果分别是6.6 ×10 -9体应变/mm、9.6 ×10-7体应变/ mm 与1.0 ×10-2体应变/mm;在此基础上, 推算出该井水位在张北地震前60 mm 的缓升型异常相应的含水层应变与应力前兆的量级为5.76×10-5体应变与2.3 kPa 。

Abstract: Sensitivities of responses of well water levels to different kinds of stress-strain are worked out from the tidal effects of well water level, loading effects of surface water body and trains of Fengzhen well.The results represent as 6.6 ×10-9 bulk strain/mm, 9.6 ×10-7 bulk strain/mm and 1.0 ×10-2 bulk strain/mm respectively.Based on the results, the corresponding strain and stress order of the aquifer around this well are then calculated for the anomalies of slow increase by 60mm of the water levels before the occurrence of Zhangbei earthquake.The results are 5.76 ×10-5 bulk strain and 2.3kPa respectively.

Key words: Well water level, Responding sensitivity, Tidal effects, Loading effects of surface water body, loading effects of trains
