福溪水库泄放洞改造金属结构布置与设计

Layout and Design of Metal Structure for Discharge Tunnel Reconstruction of a Reservoir

福溪水库为提升防洪能力,将原导流洞改建为泄放洞作为汛期预泄设施。主要介绍该水库泄放洞改造工程金属结构设备的总体布置和具体设计,并从设备布置、结构设计、启闭机选型等方面进行阐述,工程的金属结构在确保结构强度、刚度及稳定性的前提下均能符合现行规范要求。

In order to improve the flood control capacity of a reservoir,the original diversion tunnel was reconstructed into a discharge tunnel as a pre-discharge facility in flood season.This paper mainly introduces the general layout and specific design of the metal structure equipment in the discharge tunnel reconstruction project,and expounds the equipment layout,structural design,hoist selection and other aspects.The metal structure of the project can meet the requirements of the current code under the premise of ensuring the structural strength,stiffness and stability.
