| 摘 要： | 本文收集整理了2010年至2013年期间山东地区830个地震安全性评价工程的场地类型、覆盖层厚度、钻孔剪切波速、自由基岩地震动峰值加速度和地震加速度反应谱特征周期等资料,在计算出场地指数的基础上,采用回归分析方法,对特征周期与基岩峰值加速度、场地指数之间的关系进行了统计研究,并得出了三者之间的定量表达式。结果表明,特征周期与基岩峰值加速度的自然对数呈线性相关,与场地指数呈非线性相关。

| Abstract: | In this paper, we have been collected data of site type, cover thickness, shear wave velocity, seismic peak ground motion acceleration and characteristic period of the acceleration response spectrum calculated for the rock surface for 830 engineering sites in Shandong Province. On the basis of these data, site index for each site has been calculated, and with the method of regression analysis, the relations among the characteristic period, peak acceleration of bedrock and the site index are studied. A quantitative statistical relation between the characteristic period, and other parameters are achieved. The results show that the characteristic period is linearly related with the rock surface seismic peak ground acceleration, and is nonlinearly related with the site index. |
