| 摘 要： | 通过在宽长水槽中进行的单向恒定均匀流作用下，不同桩群、不同流速或不同水深情况下的圆柱桩群局部动床冲刷对比试验研究，分析试验后水槽地形变化的资料发现：圆柱桩群局部冲刷非常复杂，圆柱桩群的存在极大地改变了原有的水沙运动状态，加剧了桩群所在底床泥沙的冲淤。圆柱桩群对其所在底床冲淤影响特性不能只用桩群阻力简单解释，而与圆柱排列形式关系最为密切、影响也最大，水流流速及水深的影响实际通过圆柱桩群对流场改变的性质及程度来反映。

| Abstract: | By contrast tests on local scour around cylinder pile clusters in different conditions with different cylinder pile clusters,different velocities or water depths in an unilateralism invariableness-uniform flow flume,the data of flume topography change after testing is analyzed.The results show that the local scour around cylinder pile cluster is extremely complex,the existence of pile cluster changed significantly the original motion state of water sand,and intensified the local scour around cylinder pile c... |
