广西石埠井水位一次显著异常分析

Analysis of a Significant Anomaly of Water Level in Shibu Well, Guangxi

  • 摘要: 针对石埠井2019年8月4日后出现的多项异常现象进行现场检查,结合环境因素、气象因素、水质化验和气体检测等分析结果,认为异常的出现与区域性构造活动关系不大。其中:水位日变幅增大为仪器传感器故障所致;井水冒顶和翻花冒泡现象与井壁破裂、邕江水利枢纽大坝蓄水后邕江水位抬升以及南宁市区5—8月持续强降雨有关;观测井内出现的灰白色絮状物则可能与地下水径流经过煤系地层有关。

     

    Abstract: Based on the field inspection of several abnormal phenomena in Shibu well after August 4, 2019, and combined with the analysis results of environmental factors, meteorological factors, water quality test and gas detection, it was considered that the occurrence of anomalies had little relationship with regional tectonic activities. Among them, the increase of daily variation of water level was caused by instrument sensor failure. The shaft wall rupture, water level rise of Yongjiang river after the dam impoundment project, and continuous heavy rainfall from May to August in Nanning city resulted in the phenomenon of roof falling and bubbling of well water. The gray white floccule in observation wells may be related to groundwater runoff passing through coal measures strata.
