| 摘 要： | 结合某大型水电站地下厂房,首先采用三维有限元方法分析了其自振特性,并对其进行了共振校核。其次基于该电站的实测振动数据,分析了机组与厂房结构响应的关系。在此基础上,采用结构动力谐响应计算,对该电站厂房机墩上的垂向动荷载进行了反馈分析,并分析了厂房结构的振动响应。计算结果可为同类型厂房结构设计提供参考。

| Abstract: | Combined with a big scale underground hydropower house,the paper first analyzed its natural vibration characteristics by use of three-dimensional finite element method and carry out the check of resonance vibration. Based on the measured vibration data,it secondly studied the relationship between units and powerhouse structure. Thirdly, the paper made feedback analysis for the vertical dynamic load on unit pier and studied the vibration response of powerhouse structure. Form the numerical simulation, the response of the powerhouse structure can be known. The results can provide reference for the design of the same type of powerhouse structure. |
