桥墩周围局部冲刷的最大深度已经在实际用途中得到了理解。由于结构的复杂性，关于桥墩周围水流结构的数据还不够多。在本研究中，在直动航道中建立了圆柱形桥墩模型。在对桥墩周围的压力场和速度场进行详细测量的基础上，弄清了桥墩周围的流动结构和流体力。
Maximum depth of local scouring around a pier has been understood within the practical purpose. Because of the complexity, there are not sufficient amount of data about the structure of flow around a pier. In this research, a cylindrical pier model was set up in the straight movable channel. Based on the detail measurement of the pressure and the velocity field around it ,the structure of flow and the fluid forces acting around the pier were clarified.
