| 摘 要： | 对内河挖入式港池发生淤积的原因进行分析，认为淤积主要是由口门处的回流及浑水异重流引起的。结合港池的淤积形态在已有理论的基础上建立了淤积量计算模式，并用该方法对岳阳某港的挖入式港池进行淤积量计算，与实际淤积量相比较为吻合，验证了该计算方法的正确性。为预测内河挖入式港池的淤积量提供重要依据。

| Abstract: | Based on the analysis of the reason of sedimentation in dig-in basins,it is considered that sedimentation is brought primarily by circumfluence at the basin entrance and density flow.Combining the sedimentary form,sedimentation calculation formula is set up on the basis of the known theory.The application result of this method in sedimentation volume calculation of a dig-in basin of Yueyang port conformed well to the real measured data,thus the correctness of this method is verified.This method may serve as an important basis for forecast of sedimentation in dig-in basin of inland river. |
