摘要
桥墩冲刷一直是冲积性河流中桥墩失稳和桥梁水毁的主要原因。结合已有的研究成果对桥墩周围的水流结构、局部冲刷的发展过程、以及冲刷坑深度的影响因素的研究现状进行了详尽的介绍,并对未来的研究方向进行了展望。
The damage of biridges and piers are caused by local scour around piers mainly in rivers. The paper introduces the present situation of study on the flow structures, the development process and factors to influence the depth of local scour hole around the piers on the base of the previous research achievements.At last,the paper forecast the future study direction.
