摘要:
研究河床洼地的水流特性．在一个可调节坡度的实验水槽内设置一个接近于自然形状的洼地．应用电磁流速仪测量洼地内3个方向的流速．实验过程中，在洼地拥有铅直岸壁的一侧观测到柱状分离涡．为使洼地更接近实际，在洼地内沿铅直岸壁设置两个6 cm高的可透水石笼．设置石笼后的洼地流态变化较大，分离涡发生在石笼的对岸一侧．本实验结果为环境流体力学和河流动力学探讨洼坑水流规律提供了研究基础．
Abstract:
The hydrodynamic behavior of the open channel with pools and riffles has not yet been fully understood although pools and riffles on a riverbed can improve hydrobios habitats and restoration of canalized urban streams．The characteristics of three dimensional flow structure in the open channel with a pool were analyzed by experiment study．A nature-like pool was made on a fixed bed in a slope-adjustable flume to simulate real river channel．The three-dimensional velocities in the channel were measured with electromagnetic velocimeters．A cylindrical separation vortex was generated in the pool near a vertical wall．In order to simulate the natural flow in the pool，two 6 cm high permeable groins were set adjacent to the vertical wall．The vortexes in the pool with groins were reduced in size，and a new separation vortex appeared on the opposite side.
