摘要 基础隔震技术可以实现核电厂上部结构和内部设备、管道的标准化设计,并提高结构体系的抗震裕度。考虑到设备和管道的抗震要求,提出了一种核电厂三维基础隔震技术。首先采用单质点简化模型进行参数分析,确定了隔震层的合理参数。其次设计开发了三维隔震装置,包括厚层橡胶隔震支座和油阻尼器,并进行了相关的检测试验。最后进行了几何缩尺比例为1/15的振动台试验,模型包括三维隔震模型和传统水平隔震模型以及非隔震模型。试验证明:三维隔震系统在水平方向具备与传统隔震系统相同的隔震性能,并且可以有效地实现核电厂内部设备及管道的竖向隔震。 基础隔震技术可以实现核电厂上部结构和内部设备、管道的标准化设计,并提高结构体系的抗震裕度。考虑到设备和管道的抗震要求,提出了一种核电厂三维基础隔震技术。首先采用单质点简化模型进行参数分析,确定了隔震层的合理参数。其次设计开发了三维隔震装置,包括厚层橡胶隔震支座和油阻尼器,并进行了相关的检测试验。最后进行了几何缩尺比例为1/15的振动台试验,模型包括三维隔震模型和传统水平隔震模型以及非隔震模型。试验证明:三维隔震系统在水平方向具备与传统隔震系统相同的隔震性能,并且可以有效地实现核电厂内部设备及管道的竖向隔震。
