【摘要】：基于计算流体动力学的方法,运用三维河道水力学模型HEC-RAS(River Analyse System)分析阿尔及利贝贾亚高速公路在建项目2号互通桥梁在百年一遇的最大洪峰流量下,不同桥梁孔跨方案在相同地质条件下对桥梁最大冲刷深度的影响,对不同桥梁孔跨方案下三维河道水力学模型计算结果进行分析研究,确定经济合理的桥梁设计方案,为今后国内外同类桥梁设计的方案研究提供了新的研究方法。
[Abstract]:Based on the computational fluid dynamics (CFD) method, the 3D channel hydraulics model (HEC-RAS (River Analyse System) is used to analyze the flow of the No. 2 interchange bridge under construction project of Algeribejaya Expressway under the largest Hong Feng discharge in a hundred years. The influence of different bridge hole span schemes on the maximum scour depth of the bridge under the same geological conditions is studied. The results of 3D river channel hydraulics model under different bridge hole span schemes are analyzed and studied, and the economical and reasonable bridge design scheme is determined. It provides a new research method for the similar bridge design project at home and abroad in the future.
