白鹤滩水电站出线竖井通风设计与内衬风管施工研究
Ventilation design and construction of lined air duct for outlet shafts of Baihetan Hydropower Station
摘要：
白鹤滩水电站出线竖井深埋于地下，各段高度均超过100 m，自然通风无法满足出线竖井的通风设计要求。本文介绍了其出线竖井的通风设计方案和气流组织特点，分析了用于空间狭小且不规则土建风井的内衬风管制作方案，提出了土建风井内衬风管的吊装和拼装施工方案。

Abstract：
The outlet shafts of Baihetan Hydropower Station are deeply buried underground, and the height of each section is more than 100 m, and natural ventilation can not meet the ventilation design requirements of the outlet shafts. This paper presents the ventilation design scheme and air distribution characteristics of the outlet shafts，analyses the manufacturing scheme of the lined air duct for narrow and irregular civil wind wells, and puts forward the construction scheme of lifting and assembly of the lined air duct for civil wind wells.
