摘要

通过跟踪分析湖州地震台数字化水管倾斜仪和垂直摆倾斜仪连续2年的资料质量,发现水管倾斜仪观测精度高于垂直摆倾斜仪,并且资料稳定性逐年提高。从映震效能看,水管倾斜仪同震响应幅度远大于垂直摆,水管倾斜仪的自振周期远大于垂直摆倾斜仪而接近远震面波的周期,形成谐振,但两者的同震响应时间相当。
Through tracking analysis of record quality of digital tube tiltmeter and vertical pendulum tiltmeter over two consecutive years, it is found that the data quality archives the advanced level in international scope. It also shows that the data precision of tube tiltmeter is higher than that of vertical pendulum tiltmeter and the data stability is improving year by year. Judged by the capability of earthquake response, the co-seismic response amplitude of tube tiltmeter is much larger than that of vertical pendulum. Since the autoexcitation period of tube tiltmeter is much longer than that of vertical pendulum tiltmeter, syntony is engendered. However, the response times of two types of tiltmeters are equal.
