Research on the Protection Effect of Diversion Channel in Water Conservancy Hub Engineering Based on Concrete Hinge Rows

研究旨在探讨基于混凝土铰链排的水利枢纽工程导流明渠防护效果,以满足导流明渠在洪水期间的稳定性和安全性需求。导流明渠的防护至关重要,因其直接关系到珠江副坝的安全。研究通过模型试验和计算分析,采用混凝土铰链排作为防护方案,分析了其对洪水流速和水流流态的影响,以及其稳定性和抗冲刷能力。结果表明,混凝土铰链排能有效减小洪水流速,提高导流明渠的稳定性,同时对珠江副坝的安全性具有积极影响。综合风险评估和安全性分析,防护工程被证明是可行和有效的。

The research aims to explore the protective effect of diversion channels in water conservancy hub projects based on concrete hinge row,in order to meet the stability and safety requirements of diversion channels during floods.The protection of diversion channel is very important,because it is directly related to the safety of the Pearl River auxiliary dam.The study used concrete hinge row as a protective scheme through model experiments and computational analysis,and analyzed its impact on flood velocity and water flow state,as well as its stability and anti erosion ability.The results show that the concrete hinged mattress can effectively reduce the flood velocity,improve the stability of the diversion channel,and have a positive impact on the safety of the the Pearl River Saddle Dam.Based on comprehensive risk assessment and safety analysis,protective engineering has been proven to be feasible and effective.
