金沙江银江大件码头对航道的影响研究

The study on effect of heavy cargo wharf in Jinsha river Yin river on channel

建立了正交曲线坐标下的平面二维水流数学模型,并根据实测资料对模型进行了验证,通过不同水位条件下的起动流速分布以及相应的二维流场计算结果,对工程河段码头修建前后冲淤位置进行了定性分析,结果表明码头的修建对航道影响较小。

The plane two-dimension flow mathematical model at orthogonal curvilinear coordinates was built, and which was verified based on measured data. By calculation results of starting flow distribution at different water level condition and relative two-dimensional flow field, the siltation and erosion position before and after building of engineering reach wharf was analyzed qualitatively, the result showed that the building of wharf has little influence on channel.
