河床式水电站，水电站厂房位于河床中作为挡水建筑物的一部分，与大坝布置在一条直线上，一般只能形成50m以内的水头，随着水位的增高，其投资也增大。这种水电站的特点是水头较低，流量较大。典型例子是广西西津水电站，葛洲坝水电站等。三峡水电站属于世界上总装机容量以及总装机容量最大的坝后式水电站。
Until the present time, there is no uniform regulation about water seal layout of power station in river channel. There is no report and study about this aspect, both here and abroad.
但到目前为止,对于河床式水电站厂房坝段横缝止水布置形式还没有统一的规定,国内外在此方面的研究很少,设计中主要是根据工程经验布置。
