摘要:
采用数值模拟的方法，针对典型工程，对桥墩周围河床局部冲刷的三维流场进行了研究。通过将数值模拟所得流速场和物理模型中用ADV流速仪在实体模型中的量测结果进行对比和相互验证，结果较为吻合，同时分析了流场分布及不同方向流速对冲坑形成的作用。本文所采用的桥墩局部冲刷流场数值模拟计算方法对于深入研究桥墩局部冲刷及复杂边界流场理论具有一定的参考价值，所得流速场分布结果为浅基桥梁工程防护设计提供了参考依据。
Abstract:
Aimed at the representative project in the piers,which is protected by the downstream sediment storage dam,this paper has studied three dimensional velocity field in local scour areas around piers via mathematical simulation.The validated results are better contrasting that of the model test surveyed by ADV (Acoustic Doppler Velocimeter) while the influences of shaping eroded pits caused by the velocities in different directions are analyzed.The mathematical simulation method of velocity field in local scour pit around bridge pies can be referenced to study local scour around bridge pies and complicated boundary flowfield theory in depth.The distribution of velocity field in local scour pit near piers protected by the sediment storage dam,deduced from the paper,will provide references for defensive design of bridge projects with pies in low burial.
