摘　　要： 　通过对河道修建高桩码头前、后的流速分布及水位试验分析得出:随着桩群长度的增加,同一根垂线上的流速分布趋于均匀。对于不同的桩群长度,其水位沿程变化分布基本上相似、大小不同,桩群越长码头前沿的水位壅高值越大,其相应水位变幅也最大。建立了码头前沿的最大水位壅高值与桩群长度以及桩群宽度之间的关系式,为类似条件高桩码头的设计提供了参考。 According to the laboratory measurements of velocity and water level which were obtained before and after seting up of pile group. This paper reaches the conclusion that with the increasing of length of pile group, the velocity distribution of the same vertical line tends to distribute uniformly. The variation in water level is similar to different length of pile group basically. The higher the backwater in front of the wharf, the longer the length of pile group, and the wider the amplitude of water level. By the indoor flume experimental,the different length and width of the pile group affecting the water flow of river way were discussed. Based on the experimental data, the formula about the max of backwater height and the length and width of pile group were matched.
