千佛岩水电站泄洪建筑物水力学试验研究

Study on Hydraulic Test in Flood-releasing Structure of Qianfoyan Hydropower Station

工程中泄水建筑物与电站厂房之间容易出现跌水、侧收缩等问题,严重地影响了泄水建筑物的泄流量和电站的安全运行。结合具体工程,通过多种体型方案的比较,提出了在闸墩前加设圆墩头导墙的优化方案,为同类工程的设计、修建起到了一定的参考作用。

Abstract： Hydraulic drop and side contraction often occur between the flood-releaslng structure and power-house in many projects,which badly influence on the discharge of flood-releasing structure and the safe running of the plant. By comparing several bodily form schemes and combining a project, the optimizing scheme that a circular pier guide wall is set in the front of the pier is put forward. It can afford references to similar projects.
