为使汾河二库枢纽工程能够发挥以防洪和城市供水为主，结合发电和旅游等综合效益，设计了多种型式的金属结构设施．汾河二库枢纽工程的金属结构设计具有种类多、功能较齐全、水头较高、跨度较大和技术较先进等特点、；并在设计过程中对液压启闭机的选用、深水拦污栅的起吊方式和大跨度斜支臂弧形闸门扭角精确计算从而减小组合处错位偏差等技术问题进行了研究．
In order to enable the Fenhe II reservoir hub project to play a flood control and urban water supply, combined with comprehensive benefits such as power generation and tourism, designed a variety of types of metal structures and facilities. The design of the metal structure of the Fenhe II reservoir hub project has many kinds of features, complete functions, high head, large span and advanced technology. In the design process, the hydraulic hoist selection, deep water trash rack Lifting method and long-span oblique arm arcuate gate torsion angle accurate calculation to reduce the combination of misalignment and other technical problems were studied.
