天花板水电站厂房布置与结构设计

Powerhouse Layout and Structure Design of Tianhuaban Hydropower Station

天花板水电站厂房位于峡谷地区,河谷偏窄,地质条件较差,机组安装高程低,设计校核尾水位高。厂房设计时采取厂区建筑物紧凑布置、因地制宜的原则,在尾水渠布置、主机间整体稳定、尾水挡水结构、出线布置设计和边坡开挖支护设计上采取有针对性的措施,较好地解决了存在的问题。实践证明,天花板水电站厂房设计方案合理,为电站的顺利发电奠定了良好的基础。

The powerhouse of Tianhuaban Hydropower Station locates in a narrow valley with poor geological conditions. The installation elevation of unit is lower and the designed tail water is higher. The structures is arranged according to the principle of ＂Compacted and basing on local conditions＂. The special treatments for the arrangement of tail water channel, the overall stability of powerhouse, the tail water retaining structures, the outgoing system arrangement and the slope excavation support design are adopted to solve the main problems. The practical operation shows that the powerhouse design is reasonable.
