摘　　要：为了验证混凝土铰链排在工程实践中的防护效果,以湖北省碾盘山水利水电枢纽工程为例,介绍了其导流明渠铰链排防护设计的具体参数与结构,并结合2019~2022年汉江洪峰流量和铰链排防护区典型断面的水下地形变化情况,分析铰链排防护效果以及设计的合理性。结果表明:混凝土铰链排具有柔性防护的特性,能够适应地形冲刷变化,抗冲能力强,防护效果好,适合平原易冲刷地区大流量导流明渠关键部位的防护。研究成果可为类似工程提供参考经验。To verify the protective effect of concrete hinged mattress in engineering practice,taking Nianpanshan Water Conservancy and Hydropower Project in Hubei Province as an example,the specific design parameters and structures of concrete hinged mattress in its diversion channel were introduced.Moreover,combined with the flood peak discharge of Hanjiang River from 2019 to 2022 and the underwater terrain changes of typical sections of the hinge protection zone,the protective effect of hinged mattress and rationality of design were analyzed.The results showed that the protection effect of concrete hinged mattress was good,it could adapt to the change of terrain erosion with the characteristics of flexible protection and could resist the flood erosion,which could be applied for protection of key parts of large flow diversion channels in plain areas.The research results can provide a reference for similar projects.
