| 摘 要： | 对观测技术系统、降雨、区域应力场等干扰因素进行了排除,并调查观测井的周边环境及分析基础资料。结果表明,2011年底以来泉州局一号井水位突降为非前兆异常,造成的原因主要是周边基建干扰引起的。由于花岗岩地区特殊的岩石特征,即发育较多裂隙、微裂隙和解理,周边基建会破坏水井的承压性及封闭性,进而破坏地下水的动态平衡,建议在花岗岩地区选择水井时最好选择观测含水层与上一层非观测含水层间距较大的水井。

| Abstract: | This paper eliminated disturbances such as： observation system , rainfall and regional stress field, investigated observation environment and basic data. The result showed the main cause of suddenly-lowing anomaly in No. 1 well since 2011 is building disturbance. Because of regional petrological characteristics with more cracks and joints, the construction will break bearing and sealing property of groundwater dynamic balance. The observation well should locate between observation aquifer and non-observation aquifer with long distance. |
