乌加河地震台水平摆、水管倾斜仪同震响应对比分析

摘要

Selected 13 earthquakes' data recorded by horizontal pendulum tiltmeter and water-tube tiltmeter at Wujiahe Seismic Station from 2013 to 2015,comparative analysis of coseismic response characteristics.Analysis:for the same earthquake,horizontal pendulum tiltmeter's maximum response is greater than the water-tube tiltmeter's,and the response delay time is shorter;horizontal pendulum tiltmeter and water-tube tiltmeter's response duration and magnitude is proportional to the magnitude.The results show that the maximum amplitude,delay and duration of the same earthquake are recorded by horizontal pendulum tiltmeter and water-tube tiltmeter in the seismic station.%选取2013-2015年乌加河地震台水平摆和水管仪记录的13个地震资料,对比分析同震响应特征.分析认为:对于同一地震,水平摆最大响应幅度大于水管仪,且响应延迟时间略小;水管仪和水平摆同震响应持续时间与震级成正比.结果表明,该地震台水平摆和水管仪记录同一地震的最大响应幅度、延迟和持续时间,对远震和近震均具有不同程度的响应.
