摘要:
以某CPR1000堆型反应堆厂房的集中质量简化模型为研究对象,基于Super FLUSH软件平台,考虑结构-地基动力相互作用(SSI),并采用弹性模量模拟岩性地基线弹性特征,等效线性模拟土质地基非线性特性.建立不同地基条件的核岛厂房结构响应分析模型,从而分析不同地基条件对核岛厂房结构地震响应的影响.该模型计算结果表明:随着地基条件的变化,尤其是从岩性地基到土质地基,核岛结构响应变化明显.
Abstract:
A nuclear reactor CPR1000 calculation model of different ground conditions based on the software of Super FLUSH was established, which adopted the concentrated mass by setting energy-transmitting boundary in the limited area of foundation. The elastic modulus was used to simulate the linear elasticity of rock and the equivalent linear method was applied to consider the nonlinear characteristics of soil foundation. The seismic response models with different ground conditions were analyzed, the effects of different ground conditions on seismic response of nuclear island were investigated. The calculation results indicate: the seismic response changes obviously for the ground condition variation from soil to rock.
