摘要
采用三维有限元法计算了某水电站厂房进水塔地震作用下的动力响应,对静动力下塔体的位移和应力进行安全验算,对基础面法向力进行了强度校核。计算结果表明,进水塔结构设计合理,整体安全。
The dynamic responses of powerhouse intake tower of a hydropower station under earthquake action are calculated based on 3D finite element method, and check computation are carried out to safe displacement and stress under combinations of static and dynamic forces. Besides, normal stress strength in foundation base is also checked. The calculation results show that the design of intake tower is reasonable and safe.
