| 摘 要： | 以南水北调台儿庄泵站为研究对象,运用三维有限单元法以及反应谱理论分析该泵站的动力特性和动力响应。根据上部结构与泵站站身刚度相差较大的特点,提出了分别计算各自的动力特性,再利用反应谱理论组合法求解结构动力响应的计算方法。计算结果证明,台儿庄泵站设计合理,整体结构的抗震安全性满足设计规范要求。 |

| Abstract: | The finite element method and response spectrum theory are used to analyze the vibration characteristic and dynamic responses on Taierzhuang pump station.According to the big stiffness difference between the upper structure and the pump house in the pump station,response spectrum combination method based on individual dynamic characteristics is presented.The computation results show that the seismic safety of the taierzhuang pump station satisfies the standard requirement and its design is reasonable. |
| Keywords: | pump station finite element method response spectrum method seismic safety evaluation |
