| 摘 要： | 为比较中国、美国和法国三国在考虑核电厂土结相互作用(SSI)抗震分析方面主要规范的异同,通过对核电厂主要厂房结构应用GB 50267—1997、ASCE 4-98及RCC-G88三种规范,比较SSI阻抗函数的方法的异同,拟合便于工程使用计算刚度及阻尼系数的公式,运用ANSYS11.0通过等效简化分析,建立土弹簧-集中质量-梁模型进行模态分析,得到RCC-G88中与频率有关的阻抗函数。对比表明,对于刚度较大的核电厂主厂房土-结相互作用分析,RCC-G88反映地基动力特性,较ASC E4-98和GB 50267—1997保守。

| Abstract: | In order to compare China,the United States and France the similarities and differences about consideration of nuclear power plant soil-structure interaction(SSI).Through the analysis of main building in nuclear power plant,compare the code GB 50267—1997,ASCE 4-98 and the code RCC-G88 in impedance method,fitting formula about the stiffness and damping coefficient,the use of ANSYS11.0 build spring-lumped-beam model for model analysis,the impedances related with frequency in RCC-G88 are obtained.The SSI analysis shows that,RCC-G88 reflects the foundation soil dynamic behavior,relatively conservative than ASCE 4-98 and GB 50267—1997. |
