| 摘要: |
| 在分析崖门口航道水文、地形特征的基础上，根据河口挖槽的特点进行概化模型设计。依据试验资料，通过对挖槽水流影响因素的因次分析，提出挖槽后轴线处的流速计算式。此外，对槽内水流偏角作了初步探讨，对不同的挖槽方式进行了对比试验。 |

| Abstract: |
| On the basis of the analyses of hydrologic, topographic characteristics of Yamenkou navigation course, in accordance with the distinguishing features of the estuarine channelling, conducted the design of generalized model. Based on experimental data,through dimensional analysis of the influence factors of channelling flow, put forward the computative formula for velocities along axis after channelling. In addition, preliminary exploration of the angle of flow deflection in the channel and comparative tests of different channelling forms were carried out also. |
