西藏扎拉水电站金属结构设计

Design of metal structure of Xizang Zhala Hydropower Station

为合理布置西藏扎拉水电站金属结构,满足功能要求,介绍了扎拉水电站泄水建筑物、导流洞、电站建筑物、生态电站建筑物和鱼道等部位的金属结构设计,提出了扎拉水电站闸门及启闭设备的布置方案。结果表明:在扎拉水电站金属结构设计中,充分考虑制造和安装要求,采用简单、实用的结构设计,泄水闸建筑物空间利用率高,鱼道建筑物具有良好的生态环保价值,设计满足功能要求,结构安全可靠。研究成果可为同类工程的金属结构设计提供参考。

In order to reasonably arrange the metal structure of Xizang Zhala Hydropower Station and meet the func-tional requirements,we introduced the metal structure design of the discharge structures,diversion tunnels,power station buildings,ecological power station buildings and fishway of Zhala Hydropower Station.The results showed that in the design of metal structure equipment at the station,full consideration was given to manufacturing and in-stallation requirements,and a simple and practical structural design was adopted.The space utilization rate of the spillway gate building was high,and the fishway building had a good ecological and environmental protection value.The design can meet the functional requirements and the structure is safe and reliable.The research result can pro-vide a reference for the design of metal structures in similar projects.
