重力坝底孔与中孔主要功能、布置原则、体型设计

Main Functions, Layout Principle and Configuration Design of Intermediate Outlets and Bottom Outlets of A Concrete Gravity Dam

系统介绍大、中、小型混凝土重力坝中孔和底孔的设计,主要对其功能、布置原则、体型轮廓等。并以已建工程实例加以补充阐述,景洪水电站重力坝右冲沙泄洪底孔自投入运行以来,状况良好。

This paper systematically introduces the design of intermediate and bottom outlets of large-, mediumand small-sized concrete gravity dams, putting stress on their functions, layout principle and confi guration and shapes and bringing the completed projects in evidence. The right bank fl ushing and fl ood discharging outlets of the gravity dam of Jinghong Hydropower Plant have been under proper conditions since their operation.
