水电工程防排烟系统采用土建风道问题探讨
Discussion on civil ducts used in smoke management system of hydropower projects
摘要：
水电工程空间巨大，风道断面大，有采用土建风道的惯例，而《建筑防烟排烟系统技术标准》规定防烟、排烟系统不应采用土建风道。从水电工程土建风道的分类、结构形式、施工工法等方面，探讨了不同土建风道的特点，为工程设计采用土建风道提供参考。

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.
