| 摘 要： | 运用泥沙冲淤的二维数值模拟和半理论半经验公式,分别计算取水前后半封闭港池泥沙回淤分布和回淤量的变化。数值模拟计算得出取水前港池泥沙回淤分布较均匀,取水后港池各部区域随其水流流态而有不同的回淤率;经验公式计算表明取水后港池回淤率增加6 mm/a,取水回淤贡献率为14%。

| Abstract: | The 2-D numerical model and the semi-theoritical and semi-experiential formula are used to calculate the sedimental distributions and changes due to water intaking from the semi-closed port basin.As it is shown in the numerical calculations,the sedimental distribtuion is relatively homongeneous in the basin in the per-water-intaking,and the sedimentation rate becomes dependent upon the current field in the post-water-intaking.It is learnt from the experiential formulum results that the sedimentation increas... |
