正确判别室内断层位移测量的干扰因子是识别地震异常信息的前提。本文以新丰江站为例,详细叙述了干扰因子的判别方法及其影响方式。认为在诸多干扰中降雨对水准,温度对基线的短期影响是室内断层位移测量首要考虑的干扰关系,并提出了对短期干扰效应和长期干扰效应使用不同的排除干扰方法。 作者还提出以断层活动矢量的误差园作为识别地震异常信息的标准,并在该区的3次中强地震中得到了验证.
Correctly judging the disturbance factor of indoor fault displacement measurement is the premise of identifying the seismic anomaly information. In this paper, Xinfengjiang station as an example, a detailed description of the interference factor of the discriminating method and its impact. It is considered that the short-term influence of rainfall on leveling and temperature on many of the disturbances is the primary consideration of indoor fault displacement measurement and a different method of removing interference is proposed for short-term interference effects and long-term interference effects. The author also proposed to use the error park of fault activity vector as a criterion to identify seismic anomaly information and verify it in 3 moderate earthquakes in this area.
