基于H/V谱比法的乌恰地区场地分类研究

RESEARCH ON SITE CLASSIFICATION OF WUQIA AREA USING H/V SPECTRAL RATIO METHOD

场地条件对于地震动特性影响显著,在工程地震领域中强震记录与之对应的场地条件在研究中十分重要。利用H/V谱比法对新疆乌恰地区12个强震台站场地进行场地分类计算,并与实际钻孔剪切波速的场地分类结果对比分析,H/V谱比法和实际钻孔波速分类结果还是有很好的对应关系,为研究区域内缺乏钻孔剪切波速测试资料的场地进行场地分类提供了参考依据。

In this paper,we collected 12 strong ground motion stations of Wuqia area,using H/V spectral ratio method to study on the site classification.We compared the field classification results with the borehole shear wave velocity site classification results,there was a good correspondence between the two site classification results.It can provide a site classification reference for the areas which are lack of the borehole shear wave velocity data.
