摘　　要：采用罚单元法处理不同单元之间的协调问题 ,对三峡水电站厂房结构的两种设计方案的自振特性进行了研究。讨论了厂房上部屋面板、钢屋架、吊车梁等对三峡厂房结构自振特性的影响 。The penalty element method was used to solve the coordinate problem among different elements. The self vibration characteristics of the powerhouse structure of the Three Gorges Hydropower Station were been studied in two design alternatives. The effect of the upper roof slabs, steel roof truss and crane beam on the self vibration characteristics of the powerhouse structure of the Three Gorges Hydropower Station was discussed. The effect of connecting ways between floor slab and downstream and upstream walls of powerhouse on the calculation results was demonstrated in the calculation model.
