水電工程防排煙系統采用土建風道問題探討
Discussion on civil ducts used in smoke management system of hydropower projects
摘要：
水電工程空間巨大，風道斷面大，有采用土建風道的慣例，而《建筑防煙排煙系統技術標準》規定防煙、排煙系統不應采用土建風道。從水電工程土建風道的分類、結構形式、施工工法等方面，探討了不同土建風道的特點，為工程設計采用土建風道提供參考。

Abstract：
There are huge space and large air duct section in hydropower projects. It is customary to use civil ducts. However, Technical standard for smoke management systems in buildings stipulates that civil ducts shall not be used for smoke control and smoke exhaust system. This paper discusses the characteristics of different civil ducts from the aspects of classification, structural form and construction method of civil ducts in hydropower projects, so as to provide references for the use of civil ducts in engineering design.
