摘要
通过对云南省保山市滇14井流量测项观测资料的初步分析,发现云南漾濞Ms6.4级地震前滇14井记录到了十分显著的短临异常,异常持续时间为5~10天。对比同井其它测项观测资料,流量观测异常明显优于其它测项。从其岩土力学机制和水动力学机制探讨对流量动态能够灵敏映震的原因。建议在我国地震地下水动态观测中应强化地下水流量的观测与研究。
Based on the preliminary analysis of the flow measurement items of Well Dian 14 in Baoshan City,Yunnan Province,this paper found that the short-term and impending anomaly recorded before the M6.4 earthquake in Yangbi,Yunnan was very significant,and the duration was about 6 to 11 days.Compared with the records of other measurement items in the same well,the abnormal flow observation is obviously better than other measurement items.The reason why the flow dynamics can be sensitive to earthquakes is discussed from the mechanism of rock and soil mechanics and the mechanism of hydrodynamics,and a reasonable explanation is obtained.It is proposed that the observation and research of groundwater flow should be strengthened in the observation of groundwater dynamics in my country.
