Current Development in Behavior Study of Pile Foundation of Bridge Subject to Scouring
摘要
Abstract
Soil erosion caused by scour occurs around pile foundation of bridge and may reduce the capacity of foundations and even lead to failure of bridge. Even though many researches focus on the behavior of pile foundation subject to scouring and few are involved in the evaluation of the effect of scouring on pile foundation. However, more attentions have been paid by academic and engineering experts. Based on defects of piers, abutments and pile foundations caused by scouring, this paper focuses on the lateral and vertical bearing behavior of pile foundation subject to scouring with theoretical researches, numerical analyses and model tests, and concludes that more systematic investigations to develop more reasonable theoretical methods are now badly needed. A large amount of research works on the behavior of pile foundation, numerical analysis, model tests and even field tests should be embarked on to lay the foundation for practical methods of evaluating the safety of bridge subjected to scouring.关键词
