| 摘 要： | 为研究地震波空间相干效应对核岛厂房土与结构相互作用分析的影响,采用ACS-SASSI软件对典型的压水堆厂房的土与结构相互作用分析时,分析不同土层、不同标高处,空间相干性对楼面反应谱的影响。结果表明,在高频段考虑空间相干性,对于中硬质岩石场地和坚硬土至软质岩石场地将降低楼层响应10%～70%;在高频段考虑空间相干性,对于中硬土场地将降低楼层响应10%～40%。因此,不考虑空间相干性,其楼层响应分析结果高频段偏保守,低频段偏不安全。

| Abstract: | In order to study the effects of spatial coherency on the seismic response of nuclear island structures considering soil structure interaction analyses, in this paper, ACS-SASSI software was used to analyze the soil structure interaction of a typical PWR reactor building. Considering different soil layers and elevations, the effects of spatial coherency on the seismic floor response spectrum of nuclear island structures were evaluated. The results show that at high frequency the floor response spectrum will be reduced by 10%~70% for firm rock and Upper Bound Soft to Medium site. For soft soil sites, it will be reduced by 10%~40%. Thus, the floor response spectrum is conservative at high frequency and is not safe at low frequency without considering the spatial coherency. |
