非淹没组合丁坝局部冲蚀规律的实验分析研究

Experiment Analysis and research of Partial Erosion Lay of Non-inundation Compound Groyne

文章根据实验情况介绍、工况及对应丁坝工作性征计算结果,对非淹没组合丁坝局部冲蚀规律进行实验分析。把握组合丁坝局部冲蚀规律,对组合丁坝设计和安全管理有重要参考和应用价值。文章依托渭河中段某非淹没组合丁坝护岸工程实用资料,以实验室比尺模型实验的方式,对非淹没组合丁坝局部冲蚀规律开展专题实验研究,分析组合丁坝工作特性,探讨其冲刷流性征,以为同类工程应用提供研究和技术参考。

Based on the experimental introduction,engineering condition and corresponding calculation results of groin work characters,this paper analyzes the experiment about partial erosion law of non-inundation compound groyne.It is great reference and application value for the design and safety management of composite groin to grasp the local erosion law of composite groin.According to the practical data about a non-inundation composite groin bank-protection project located in middle section of the Wei river,this paper carries out a special experimental study on the local erosion law of the non-submerged combined spur dike by means of the scale model experiment in the laboratory,and analyzes the working characteristics of the combined spur dike,also discusses its scour flow characteristics,so as to provide research and technical reference for similar engineering applications.
