摘要
针对某核电厂结构,在考虑土-构相互作用(SSI)的情况下,分别对核岛的抗震和隔震结构进行地基参数的敏感性分析,探讨不同厂址下地基岩土参数的不确定性对某核岛厂房的楼层反应谱(FRS)的影响。采用ANSYS有限元软件建立核岛厂房的集中质量有限元模型及隔震支座单元,再运用ACS SASSI有限元软件基于子结构法的方式来考虑SSI效应,通过FRS及减震系数等揭示了地基岩土参数的不确定性对核电厂地震动响应的影响。
For a nuclear power plant,basis considering the soil structure interaction,the sensitivity analysis of the foundation parameters for the seismic and isolation nuclear power plant is carried out respectively,and the influence of the uncertainty of the foundation parameters on the floor response spectrum of a nuclear power plant is discussed under different sites.Using the ANSYS finite element software to establish the concentrated mass finite element model and isolation bearing element of the nuclear power plant,then taking the ACS SASSI software to consider SSI effect basis the substructure method,and through the FRS and damping coefficient to reveal that the influence of influence of the uncertainty of the foundation parameters on the seismic response of the nuclear power plant.
