doi:10.3969/j.issn.1674-0696.2013.01.13

Abstract

Abstract: In order to research the wind velocity field of embankment，infinite element models were built and wind velocity field of different height embankment was simulated． Field testing methods were also employed to measure wind velocity and the simulation results were verified． Wind velocity area which affected driving safety was calculated． The results show that the higher the embankment is，the higher the local area wind velocity is，especially in windward shoulder and travel lane． The results also provide theory bases for driving safety in cross wind．

Key words: highway engineering, driving safety, field test and simulation, wind velocity field, cross wind

摘要： 为研究侧风环境下路堤风速场,建立了有限元模型,对不同高度路基风速场进行了仿真分析；现场实测了侧风环境下的路基风速变化规律,验证了仿真结果的正确性。提出了影响行车安全的计算风速区域。结果表明: 路基越高局部风速的增强就越大,上风侧路肩和行车道风速增强最明显,对行车安全影响越大。研究结果提供了侧风环境下高大路堤行车安全的理论基础。
