荷载变化对张家口地震台伸缩仪异常的定量分析

Quantitative Analysis of Load Variation on Telescopic Meter Anomaly of Zhangjiakou Station

    摘要
  • 摘要: 为做好震情跟踪及异常性质研判工作，河北地震台联合中国地震台网中心、张家口地震监测中心站进行了详实的现场踏勘，并利用三种荷载计算模型对可能造成该影响的干扰源进行定量计算。根据干扰模型计算结果、干扰与异常出现的时间相关性，综合分析认为：张家口台伸缩仪NS分量记录到的异常变化现象非建筑施工干扰造成，为地壳真实运动的可能性较大。

     

    Abstract: In order to track seismic situation and analyze abnormal properties, Hebei seismic station, China Earthquake Networks Center and Zhangjiakou Earthquake Monitoring Center Station worked together to conduct a detailed site visiting. We use three kinds of three-dimensional load model to quantify the potential interference sources, which may have caused the effect. According to the model calculation result and time correlation between the interference and the occurrence of anomalies, I think that abnormal changes of the extensometer in Zhangjiakou seismostation is not caused by the interference of construction, which is more likely to be the real movement of the earth.
