THE CONTRACT ANALYSIS OF OBSERVATION DATA BETWEEN DSQ WATER PIPE AND SQ-70 QUARTZ TILTOMETERS IN KUERLE SEISMIC STATION
Zhang Wen-lai · Inland Earthquake · 2006
By the principle of DSQ water pipe and SQ-70 quartz horizontal pendulum tiltometers,uniting the actual observation,we analyzed contrastively the data recorded by the two set of tiltometers in Kuerle seismic station.Through the analysis of the trend and the synthetic vector of the ground tilt,we obtained that the observation results of two sets of tiltometers are basically consistent. They can reflect well the change characteristics of the tilt in the monitor and observation region.The result of tide analysis about two sets of tiltometer is consistent with the local structure environment.However,the observation precision of water pipe tiltometer is obviously higher than one of the horizontal pendulum tiltometer.
