关于港湾围堰中泥水混合物流动的计算

Calculation of the Mud Mixture Flow in Harbour Cofferdam

围堰充填是近代港湾建设的一种新型方法，海底泥水混合物在围堰中边流动、边沉降，是一个复杂的两相流动．本文以大连港大窑湾港区充填沉降流动为基础，用流网法对围堰中混合物的速度分布与浓度分布进行了预估计算，所得结果与模型实验结果吻合很好．

Cofferdam filling is a new technology in the construction of modern harbour.The movement with precipitation of the mud mixture from seabed is a complicated two - phase flow in the cofferdam. Based on the cofferdam at Dayaowan harbour district, the distribution of the velocity and the concentration of the mixture flow in the cofferdam are calculated by means of flow net in this paper. The result of the calculation is relatively identical with that of the experiment.
