摘要
针对闽清梅埔观测井在2009年8月出现的水位大幅突降以及波动现象,通过观测仪器检查和水位值校测、降水和气压资料分析,以及周边抽水等环境干扰因素的排查等,没有找出可能的影响因素。但最后通过对测点附近的深入调查,寻找出是由于观测围墙下的暗沟内出现裂缝导致井水泄露引起水位下降的原因。本项工作表明,深入细致的调查研究是落实观测异常现象的关键环节。
The sharp dips and fluctuation phenomenon of water level in Meipu well in Minqing county appeared in August,2009.Through observation instrument examination,water level data calibration,precipitation and pressure data analysis,and the investigation of other environmental disturbances such as pumping in surrounding,the possible factors were failed to find.In the end,the reason was found out by further investigation.Because the well water leakage of the underground drain under the wall caused by cracks induced the water level decline.It shows that intensive research is the key to implement the abnomal observation phenomenon.
