| 摘 要： | 桥梁墩台抗水毁能力的评价首先必须明确设施的结构模型和受力模型,在此基础上通过各种方法分析各类设施的抗水毁能力。应用大型流场分析软件FLUENT,耦合求解对桥墩附近三维流场进行合理模拟,得出剪应力的分布特征,为河床冲刷分析和合理防护措施的制定奠定基础。 |
| 关 键 词： | 桥墩 三维 流场 |

| Abstract: | To evaluate the capability of piers and abutments against damage by water,first of all the structural model and force model of facilities must be clear and based on which various methods are incorporated to analyze the capability of all facilities against damage by water.In this paper,a large-scale stream field analysis software FLUENT and a coupling solution are applied to reasonably simulate three-dimensional stream fields around piers,as a result the distribution features of shearing stress are obtained,laying a foundation for analyzing river-bed scouring and establishing rational preventive measures. |
| Keywords: | pier three dimensional flow field |
