摘 要: 以一水电站地下厂房为研究对象,分析厂房上部结构可能出现的各种边界条件,重点是结构与围岩的连接状态。采用大型通用软件ANSYS对三维有限元模型的选取范围和各种边界条件进行数值计算,分析结构的动力特性。并根据共振校核和动力响应的计算结果,对各种边界条件进行综合评价,选出优化方案,为结构边界型式的设计提供合理依据。
关 键 词: 专门水工建筑物;水电站;边界条件;共振校核;动力响应

Abstract: In this paper, taking one plant underground hydropower station as a case, the different boundary conditions were analyzed. The emphasis of the boundary conditions was how the structure connects with the rock mass. Using ANSYS software, different models were calculated and analyzed. According to the results of resonance check and dynamic response, various schemes were appraised. This study is helpful to how to select the rational boundary of the structure.
Key words: special hydraulic structure; hydropower station; boundary condition; resonance check; dynamic response
