| 摘 要： | 根据思贤滘的水文泥沙、地形和底质资料,分析了思贤滘的河床底质类型、分布规律、沉积物粒度组成、重矿物含量以及河床演变特征等,讨论了思贤滘的泥沙运移特点,指出西江和北江的推移质均已进入思贤滘,但未通过,因此,对思贤滘凹岸堤围的险段岁修工程不容忽视;并对思贤滘的整治规划提出了不设闸的刍议。

| Abstract: | Based on the data of currents, sedimentary movements, topographic and sedimentary types in Sixianjiao, this paper analyses the distribution of sedimentary types, grain sizes, contents of heavy minerals and features of topographic changes. This paper also discusses the features of sedimentary transports, and points out that the bed loads of both Xijiang and Beijiang Rivers have entered into Sixianjiao channel, but have not passed away. The embankment of concave bank in Sixianjiao should be improved. For the realignments of Sixianjiao channel, a project without floodgate is suggested. |
