杨房沟水电站地下厂房风罩及机墩混凝土结构动静力受力特性分析

Analysis on dynamic and static mechanical characteristics of concrete structure of hood and turbine pier in underground powerhouse of Yangfanggou hydropower station

采用ANSYS大型通用软件对杨房沟水电站地下厂房结构进行三维有限元分析,通过整体模拟典型机组段混凝土结构,进行多种组合工况下静力及动力计算,分析厂房风罩及机墩的受力特性,验证其结构设计的合理性,供同类型地下厂房结构计算参考。

By using ANSYS software to simulate the concrete structure of typical unit section,the structure of underground powerhouse of Yangfanggou hydropower station is analyzed.The calculation of static and dynamic forces under various combined working conditions is carried out to analyze the mechanical characteristics of the hood and turbine pier and verify the rationality of the structure design,which can be used as a reference for the structure calculation of same type underground powerhouse.
