| 摘 要： | 通过在宽长水槽中进行的不同排列桩群在不同流速、不同水深的单向恒定均匀流作用下的动床冲淤对比试验研究，经比较分析试验后水槽地形变化的数据资料发现：桩群局部冲淤非常复杂，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，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，而与桩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是通过桩群对流场的改变来实现的。

| Abstract: | The contrast tests on the local deposition and scour around various pile clusters with different arrangements are performed in a wide and long flow flume,in the cases of various velocities or water depths,under unidirectional steady uniform flow.Through analysis of the topography variation of the flume,it is shown that the local deposition and scour around pile cluster is extremely complex;the existence of the piles would enormously changed the original moving-conditions of flow and sand,and would had inten... |
