地下厂房在峡谷高坝水电站枢纽布置中的优势

The superiority of underground powerhouse in the general layout of hydro station with high dam in a narrow gorge

根据近年来在峡谷地区建混凝土高坝时越来越多地采用地下厂房布置的事实 ,从施工导流、泄洪消能、泄洪雨雾影响、碾压混凝土快速筑坝、地下厂房施工水平提高及缩短建设周期、节省工程投资等方面 ,用大量的工程实例 ,论证了地下厂房相对于坝后厂房布置的优越性。

Based on the facts that more and more high concrete dams built in gorge areas adopts the layout of underground powerhouse in past years, the author uses a lot of actual project examples to proof the superiority of the layout of underground powerhouse to that of powerhouse at dam toe, viewed from construction diversion, flood releasing energy dissipation, impacts of rain and fog caused by releasing flood, quick RCC construction, construction level enhancement of underground powerhouse, the shortened construction period and investment saving.
