PRELIMINARY ANALYSIS OF THE INFLUENCES OF PUMPING ON STRAIN OBSERVATION

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.
