【摘要】 针对某电厂基础位移的发展情况 ,用非线性全过程分析方法分析了主厂房框排架结构在基础位移作用下发展到未来某时点的结构状态和自振特性 ,采用振型分解反应谱法分别计算了此时结构遭遇多遇小震、设防烈度地震和罕遇大震的结构响应 ,给出了主厂房结构的震害预测结果 ,可供电厂抗滑治理工作和临危预报参考更多还原

【Abstract】 According to the development of the foundation displacement of a certain power plant,the main factory building’s structure state and self shake property are analyzed by the full range nonlinear anlaysis method while the foundation displacement reaches a future amount,and the structure responses of multiple small seism,fortifying intensity shake and unusual large earthquake are computed respectively by the modal decomposition response spectrum method.The given results of the shake calamity forecast can be used in works of mountain slippage control and critical states forecast.更多还原
