摘要
对山西离石中心地震台水管仪与水平摆倾斜仪记录到的同一地震的地倾斜进行对比分析,探讨同震响应的基本特征。结果表明,两套仪器的地震延迟时间、同震响应持续时间与震级及震中距均成正比;水管仪的变形幅度与震级成正比,与震中距成反比;水平摆倾斜仪的变形幅度主要与震级有关,与震中距也有一定的关系。
By comparing ground tilts of the same earthquake recorded both by water tube tiltmeter and horizontal pendulum tiltmeter at Lishi Central Seismological Station ,the basic characteristics of coseismic response are discussed .The results show that delay time and duration of coseismic response of the earthquake recorded by both kinds of instruments are proportional to magnitude and epicen-tral distance .The deformation amplitude of water tube tiltmeter is proportional to magnitude and is inversely proportional to epicen-tral distance ,while the deformation amplitude of horizontal pendulum tiltmeter is mainly related to magnitude and is related with epi-central distance more or less .
