【摘要】 根据浑水和清水模型试验,分析了挖入式港池轴线与主流在不同夹角θ的情况下的回流水力特性、不同θ和主流含沙量与港池布置形式时港池淤积强度、淤积量和淤积分布情况,所得到的θ与淤积之间的变化关系可为内河挖入式码头的合理布置提供重要依据。研究结果与现场调查资料进行了对比,吻合较好。更多还原

【Abstract】 Based on the turbid and clear water model tests,the hydraulic properties of return water when the axis of an excavated-in basin forms different θ angles with the main stream;and the siltation intensity,volume of silt and distribution of siltation,when the layout of the excavated-in basin is designed,related to different θ angles and the quantity of sediments in the main stream are analyzed.The relationship between θ and siltation thus obtained can provide an important basis for rational layout of excavated-in harbour basins on inland rivers.The results of the research are compared with the data of field investigation and are found to tally well with each other.更多还原
