摘 要: | 通过对串列双圆柱不同间距时的流速分布进行试验分析,得知水流进入桩柱间隙区域后,正对桩柱的垂线流速分布由对数分布变为S型分布.沿横断面方向,流速改变形式十分相似,各曲线分布趋势沿水槽中心呈对称分布.对于不同间距,对水流影响不同,间距越大,桩周围流速减小幅度越小,流速改变波及面越小.本次试验的分析结果为码头工程设计提供了参考.

Abstract: | The velocity distribution of serial two-cylinder at different spacing was tested and was informed that when the water flows into the gap region of piles,vertical velocity distribution which is behind the piles becomes S-type distribution from logarithmic distribution.Along the cross-sectional direction,velocity change in format is very similar.The trend of the curve distribution shows symmetrical distribution along the center of sink.For different spacing,there are different impacts on the water,the greater... |
