摘　　要：介绍了一种新型桥墩即多腹薄壁墩的局部冲刷试验成果．认为桥墩周围的水流以绕流桥墩的相对较强的马蹄型漩涡系为主要特征．并讨论了冲刷过程，给出了预测冲坑深度及大小的关系式，可供估算同类型桥墩的冲刷参考．An experimental investigation of local scour around a new type bridge pier under a clear water regime is presented.The main characteristic feature of flow is relatively large horseshoe vortex flow along the circumference of the pier.And the procession of scour is discussed in this paper.Equation for predicting the depth and area of local scour hole is presented.It is significant for evaluating the potential for scour around this type pier.
