摘要：
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. © 2019, Editorial Department of Journal of Southwest Jiaotong University.
