摘要
分析了泰安台YRY-4分量应变仪自2009年7月底出现的固体潮畸变现象,与体应变、伸缩仪和水管仪同步畸变进行对比,对异常现象进行了落实。通过调查,落实了应变固体潮畸变现象是由附近居民新井抽水干扰所致,并初步分析了抽水对不同应变观测的影响程度及探头附近的地质结构。
The solid tide aberrance of YRY-4 component strain gauge has been appearing since the end of July 2009 in Taian seismic station.In this paper,we analyzed the solid tide aberrance and compared it with the synchronization aberrance of body strain,tensometer and water tube.Our survey result shows the solid tide aberrance was caused by the pumping of vicinage.We also preliminary analyzed the influence of pumping on different strain observation and the geological structure around the probe.
