摘要:
根据黏弹性人工边界的基本原理,结合有限元分析软件ABAQUS和MATLAB辅助程序,在地基有限区域上添加黏弹性人工边界并实现极限安全地震动的输入。基于ABAQUS软件平台,对CPR1000安全壳构建了土-结构相互作用体系的数值模拟模型,分析其在极限地震动下的动力响应,并将计算结果与考虑刚性基础的安全壳结构响应数据进行对比。结果表明:核电站CPR1000安全壳结构在极限安全地震动下仍能保持良好的密闭性。考虑土-结构相互作用后分析所得安全壳结构受到的应力、加速度峰值和相对位移均有所增大,使用刚性地基模型要偏于危险。
Abstract:
According to the fundamental principle of viscoelastic artificial boundary, the applications of viscoelastic boundary and the seismic motion input were implemented by using ABAQUS together with MATLAB program. A numerical model of soil-structure interaction system for CPR1000 nuclear power plant containment vessel was built in the platform of ABAQUS software. The seismic response analysis was carried out subjected to the ultimate safety ground motion, and the analysis results were compared with the data of dynamic response under the assumption of rigid ground. The containment structure could keep airtight under the ultimate safety earthquake load. When the soil-structure interaction was taken into account, the stress, seismic peak acceleration and relative displacement of the containment structure were increased. Therefore, it was more dangerous to use the containment model without considering the soil-structure interaction in structural dynamic response analysis.
