The tail tunnels with sloping ceiling is a new bodily form of pipeline for hydro-power stations. In the specific conditions, it can replace the surge tank of tailrace tunnel .It is applicable specially, if the water lever fluctuates greatly in lower reaches of a river and the length of tailrace tunnel system is between 150m and 600m.

变顶高尾水洞是一种新型的水电站管道体型，它在特定条件下能够取代尾水调压室，尤其适用于下游水位变幅大、尾水系统长度在150—600m之间的情况，从而节省较多的工程量，加快施工进度。

With the swift development of the hydroelectric project in our country, a set of large or extraordinary hydropower stations are being designed or constructed, such as the Three Gorges hydropower station, Longtan hydropower station, Xiangjiaba hydropower station, Xiaowan hydropower station, Pengshui hydropower station etc. All these hydropower stations adopt underground workshop, and have long diversion pipe system, and have one or two surge-chambers or adopt tailrace tunnel with sloping ceiling.

随着我国水电事业的迅速发展，一批大型、特大型水电站正在设计或处于待建之中，如三峡水电站、龙滩水电站、溪洛渡水电站、向家坝水电站、小湾水电站、乌江彭水水电站等，这些电站多采用地下厂房，具有较长的引水发电系统，并且设有调压室或采用变顶高尾水洞。
