摘要:
介绍了溧阳地区强震动台站分布情况,对其近年来获得的强震动记录进行初步分析,采用水平竖向谱比法研究其中3个台站的场地特征。利用卓越周期划界法对台站场地进行了初步的类别划分。结合典型台站场地的钻孔资料计算卓越周期和划分场地类别,并进行对比分析。研究结果表明,基于强震动记录的HVSR曲线的卓越周期和谱型能够较好的体现台站的场地特征,且HVSR法能突出不同场地的地震反应特征。
Abstract:
The distribution of strong motion stations in Liyang, Jiangsu Province was first introduced in this paper. The strong motion records collected by these stations in recent years were primarily analyzed. The site characteristics of 3 of the stations were discussed using the horizontal vertical spectrum ratio(HVSR)method. A primary classification was carried out on the station sites by using predominant period method. The borehole data, calculated predominant period and field classification of typical stations were compared and analyzed. Results show that the predominant period and spectral model of the HVSR curve based on strong motion records can better reflect the field characteristics of stations. The HVSR method can highlight the seismic response characteristics of different sites.
