摘　　要：以十三陵抽水蓄能电站地下厂房为原型,对其不同的结构形式作了动力分析研究,指出这类厂房结构的减振设计的有效措施是加强楼板的约束和提高楼板的法向刚度;由于机墩刚度较大,因此机墩局部削弱的不同拆卸方案对整个结构的动力特性影响不大;而中拆方案对机墩的刚度削弱最大,对减振设计最为不利.Dynamical property and response of the underground powerhouse of Shisanling Pumped Storage Power Station is studied for its different structural patterns. The results indicate that the best way to reduce the vibration of the powerhouse is to reinforce its restriction of the floor and enhance its normal rigidity. The partial weakening of the generator frustum have no much effect on the dynamical property for its large rigidity; on the contrary, the way to disassemble from the middle will be the most disadvantageous for the earthquake control.
