| 摘 要： | 对桥渡附近的河床变形进行了实验研究,认为在桥墩走向与主流方向存在一定偏角时,桥墩附近的水流结构和河床变形将会不同于没有偏角时的情况,如增大阻水宽度,起到导流作用,使局部冲刷坑增大变深,以及能使下游一定范围内主流位置和深槽位置向某一侧发生偏移.

| Abstract: | An experimental research on river bed deformation near piers is reported in this paper.The flow structure and river bed deformation near piers when an angle exists between the trend of piers and the direction of main-flow will be different from those when the angle equal to zero,such as the flow-obstructing width will increase,the diversion function will occur,the partial scouring pits get larger and deeper,and the main-flow and thalweg within a certain distance downstream the piers will deviate to one side. |
