厦门本岛场地剪切波速相关性研究
|
摘要
本文搜集整理了厦门本岛202个钻孔资料,分别对场地不同土类剪切波速沿深度的分布进行了数理统计,回归了各类土随深度的相关关系,并对精度进行了随机检验。其次,建立了厦门场地不同深度等效剪切波速Vsz与Vs20和Vs30的相关关系,并与美国加州和日本相应相关关系进行了比较。研究结果表明,厦门岛与美国和日本等强震丰富地区的Vs20和Vs30相关关系很一致,为参考上述两地区按Vs30估计场地地震反应提供了依据。
In this paper,total 202 borehole shear wave velocity data are collected. The correlations between velocities of different soils and depths are statistically analyzed and validated by random selected borehole data. Then,the correlation between Vs30 and equivalent velocity of less than 30m( Vsz) in Xiamen Island is established and compared with those in California,U. S. and Kiknet sites in Japan. The results show that there are little difference in those correlation among Xiamen Island,California and Kiknet sites. So the research results about Vs30 and site amplification in California and Japan Kiknet sites can be easily applied in Xiamen Island.
