吉布洛水电站厂房布置及设计优化

Powerhouse Layout and Design Optimization of Djiploho Hydropower Station

赤道几内亚吉布洛水电站为我国援非工程之一,属于赤道几内亚国家电网的骨干电源,电站为低坝引水式电站,总装机容量为120 MW,装机4台,单机容量30 MW。电站结构为半地下式厂房,为大跨度、高边墙结构。设计采用外排水、设置后浇补偿收缩混凝土等优化措施,优化了电站结构,通过这些优化措施,降低了工程造价、保证了施工进度,为水电站的设计提供了良好的工程实践经验。

Djiploho hydropower station of Equatorial Guinea is one of the Chinese-aid-to-Africa projects,which is the core power source of state power grid of Equatorial Guinea. The station is a low dam diversion-type station, with a total installed capacity of 120MW（4 units in total with the single capacity of 30MW）. It has semi-underground pow-erhouse, great span and high side-wall structure. The structure of powerhouse is optimized by the exterior drainage design,post-pouring of compensated shrinkage concrete and other optimization measures,which greatly reduce the project cost and guarantee the construction schedule,and can be well referenced by similar projects.
