摘要:
统计近6年来云南石林井水位记录到的同震响应情况，结合实际案例对石林观测井进行同震响应特征分析及机理研究，初步探讨得出远大地震时，表现为水位快速高频振荡、且可多次振荡，逐步衰减，再恢复正常，近距离大地震时，表现为水位出现阶升、阶降变化，两者持续时间及振幅均与震级、井震距有关。结果表明石林井水位的同震响应震幅的变化与井震距和震级有相关性，但不完全是线性的关系。同震响应时间都晚于地震发生时间，有滞后性，震级、井震距与滞后时间三者的关系正相关，震级越大，距离越远，滞后时间越长，震级越小，距离越近，响应时间越短。
Abstract:
Based on the coseismic response recorded by the water level of Shilin well in Yunnan Province in the past six years， this paper analyzed the characteristics and mechanism of the coseismic response of Shilin observation well in combination with actual cases. It was preliminarily discussed that the water level showed rapid high-frequency oscillation and multiple oscillations during distant major earthquakes， gradually attenuated， and then returned to normal. In short-distance major earthquakes， the water level showed steps up and down. The duration and amplitude of both were related to the magnitude and well-to-epicenter distance. The results show that the coseismic response amplitude of water level of Shilin well is correlated with well-to-epicenter distance and magnitude，but it is not completely linear. The coseismic response time is later than the time when the earthquake occurs， and there is a lag. The relationship between magnitude， well-to-epicenter distance， and lag time is positively correlated. The larger the magnitude，the farther the distance，the longer the lag time；the smaller the magnitude，the closer the distance，the shorter the response time.
