摘要
针对信宜井水位2018年8月中旬快速下降后又转折上升的异常变化特征,通过实地异常调查和以往的震例总结,建立水位与降雨量关系的多元回归方程,综合分析该井水位异常原因。初步判定水位快速下降后又大幅回升有多个影响因素,一是附近工地抽水与施工爆破可能导致了水位下降;二是水位大幅度回升并不只是由降雨造成,还有别的干扰因素。通过此次信宜井水位异常变化的调查,形成的分析过程和方法,有助于今后此类水位异常的判别。
In view of the abnormal change characteristics of water level of Xinyi well during mid-August 2018 with a rapid decline and then a turning rise,based on field anomaly verification and summary of previous earthquake cases,this paper establishes a multiple regression equation of the relationship between water level and rainfall,and comprehensively analyzes the cause of the well water level abnormality.It is preliminarily considered that there are multiple influencing factors for the sharp rise after the rapid decline of the water level.One is that the pumping and blasting of nearby construction sites may have caused the decline of water level,and the other is that the sharp rise of the water level is not only caused by rainfall,but also other interfering factors.The analysis process and method formed during the investigation of the abnormal changes of water level of Xinyi Well will help to distinguish such abnormal water level in the future.
