Design Characteristics of Ellipse Powerhouse in Zhongjuntan Hydropower Station

介绍高变幅洪水位作用下椭圆形厂房布置及结构设计特点:同周长的椭圆形厂房比同周长的矩形厂房面积约大1/3,可改善厂内工作条件和机组运行条件;利用椭圆形结构的拱薄壁结构承受外水压力,结构受力情况明显改善,相对传统的矩形厂房,可节省工程造价10%～15%。

Introduces the design characteristics in layout and structure of ellipse powerhouse under the flood action with large variation amplitude. That's, comparing with rectangular powerhouse with the same circumference, an increase of about 1/ 3 in powerhouse area is obtained, which facilitates the working conditions both for equipment and operators, meantime, structural loading situation is greatly improved by using the arch thin wall of the ellipse structure to take the pressure from outer water. Moreover, project costs of the ellipse powerhouse is 10%～15% less than that of the traditional rectangular one.
