场地脉动卓越周期在工程抗震中的应用

THE APPLICATION FOR THE PULSANT PREDOMINANT PERIOD OF THE SUBSOIL IN ENGINEERING SEISMICS

摘要: 根据工程项目场地地震安全性评价工作中所进行的场地脉动卓越周期测试和剪切波速测试结果,以及地震反应分析计算结果的研究分析,根据现行工程抗震设计规范,将场地脉动卓越周期作为工程抗震中场地土类型、场地类别划分的参考标准,以及与工程场地地震反应分析计算结果回归分析,结合场地地震危险性概率分析,估算场地地震动峰值加速度,应用于工程抗震设计中。

Abstract: on the test results of subsoil pulsant predominant period (SPPP)and shear wave velocity,through analysis to the earthquake response,we take SPPP as the criterion of the type of site soil and the classification of site.It can be used in the regression analysis of earthquake response for an engineering site.Combined with the probabilistic analysis to earthquake risk,it can also be used in the design of engineering seismics.
