摘要
不同类型的丁坝对沿河公路路基的防护效果不同.应用大型流场分析软件FLUENT,采用现代三维运动界面追踪技术VOF(volume of fluid)方法和标准k-ε模型耦合求解,对三种不同类型丁坝的绕流流场进行了分析比较,指出漫水丁坝和透水丁坝是较为合理的丁坝形式,从而为丁坝的设计和建造提供了理论分析的基础.
Different types of spur dikes have different effects on protection of subgrade scour along river. Modern 3D moving interface tracing technology - volume of fluid （VOF） method and standard κ-ε model integrated in FLUENT, are jointly used in the present study to numerically simulate the flow field of three types of spur dikes. The calculated results indicate submerged and seepage spur dikes are rational form for prevention of subgrade scour, consequently laying a theoretical foundation of the design and construction of spur dike.
