摘要: 冲刷是导致桥梁结构破坏的关键因素之一，从机理、计算、模型、探测及防护、承载及变形等5个方面较为系统地对桥梁基础冲刷的研究和实践进行了综述. 首先，在总结现有桥梁基础冲刷机理的基础上，对比分析了已有冲刷计算公式，阐明不同公式的局限性；随后，通过综述桥梁基础冲刷在试验和数值方面的研究，指出模型试验及数值模拟方法存在的不足和问题；此外，讨论了桥梁基础冲刷探测方法及主要的冲刷防护措施，比较了各种探测方法的优缺点及各种防护措施的作用原理，概述了冲刷对桥墩承载及变形特性的影响；最后，指出了桥梁基础冲刷方面值得进一步研究的问题和发展方向.Abstract: Scour is one of the key causes of bridge failures. This paper presents a comprehensive review of the current research on scour at bridge foundations from five aspects: mechanism, calculation, modelling, monitoring and countermeasures, load and deformation. Based on the mechanism of scour around bridge foundations, different formulae developed for calculating scour depth are compared and analysed, and the limitations of the existing formulae are summarized. The results of numerical and laboratory models established for the scour studies are presented, along with a summary of the experimental and simulation limits. Moreover, a summary of monitoring methods with their advantages and disadvantages, as well as the countermeasures with their mechanisms and the effects on lateral load and deformation of bridge pillars is given. Finally, the future research trends of bridge foundation scour are presented, which provides some reference for research, design, and construction.

表 1 中美桥梁基础冲刷计算公式的优缺点对比
Table 1. Advantages and disadvantages of calculation formulae of China and US
计算公式 优点 缺点 中国规范 清水冲刷和动床冲刷采用不同的计算公式，两者区分更加明显；修正式65-1和式65-2选择两者估算值中
最不利的一种；与现场实测数据结果的拟合较好.参数较多，且大部分参数的取值存在较大的不确定性；同一公式两边的量纲不一致，不同公式右侧的量纲也不相同，公式经验性极强；未考虑漂流物墩前聚集对桥墩局部冲刷的影响；复杂群桩桥墩冲刷的计算结果对设计和工程实际的参考价值有限. 美国规范 参数较少，简化，便于理解和应用；公式两边量纲一致，引入弗劳德数，使水力学方面的物理意义更明确；对于复杂群桩桥墩冲刷的叠加法，概念明确，实现了与简单桥墩冲刷的统一计算；能考虑漂浮物聚集对桥墩局部冲刷的影响. 未涉及河床泥沙颗粒对局部冲刷深度的影响，仅仅通过系数考虑河床地貌的影响；计算结果偏于保守；与现场实测数据的拟合误差较大.
