汾河二库枢纽工程金属结构设计与研究

Design and Study of Metal Structure in FenheⅡ Reservoir

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 make the Fenhe ⅡReservoir Project bring multiple benefits in flood prevention, mu-nicipal water supply, power generation and tourism, varied models for metal structure are designed. The metalstructure for hydraulic complex project have the characteristics of a great variety, complete function, higherwater level, major span and advanced technology. In the process of design, the problem of selection of hy-draulic hoist, the hoist way of the deep-water trash rack, the accurate calculation of the torsional angle of themajor span and raking strut radial gate is studied.
