大化水电站接头土坝下游护坡改造加固设计

Reinforcement Design of Slope Protection in Downstream of Joint Earth Dam of Dahua Hydropower Station

结合大化水电站运行资料及扩建厂房接头土坝段破坏现状,对接头土坝段下游护坡的破坏成因进行分析,进而对其下游护坡改造加固方案进行论述分析。分析结果表明,接头土坝段下游护坡采用混凝土护坡可满足非正常运行防冲要求,是合适和安全的。

Based on the operation data of Dahua Hydropower Station and the damage status of the joint earth dam section of the extension plant, the cause of the damage of the downstream slope protection of the joint earth dam section is analyzed,and then the reinforcement scheme of the downstream slope protection is discussed. The analysis results show that the use of concrete slope protection at the downstream slope of the joint earth dam section can meet the prevent erosion requirements for abnormal operation and is suitable and safe.
