水电站坝后背管工程技术分析

Hydropower dam engineering and technical analysis of the back tube

坝后背管作为一种相对新兴的水电站发电引水管道管型,近半个世纪以来有了长足的发展,成为巨型和大型水电站工程中的主力管型。全世界利用这种管型的水电站和抽水蓄能电站的总装机容量约达40000MW,我国约占60%。

The dam back tube takes one kind of relatively emerging hydroelectric power station electricity generation pilot pipeline to cast, since near half century had the considerable development, becomes giant and in the large hydroelectric station project main force casts. The world uses the hydroelectric power station which and the pump this kind casts gathers can the power plant total installed capacity approximately reach 40000MW, our country approximately composes 60%. This article makes a simple analysis on the hydroelectric power station dam back tube engineering technology, only for everybody reference.
