| 摘 要： | 针对少沙河流上船闸航道泥沙淤问题研究资料甚少的情况，采用物理模型试验方法，研究了贵港枢纽船闸引航道水流泥沙运动规律，分析了引航道淤积的机理及特点，得出了３个特征年份引航道泥沙回淤量及引航道口让区最大淤积厚度，研究表明少沙洒流上的船部引航道淤积仍然是不可忽视的问题，建设中必须考虑相应的清淤措施。

| Abstract: | Guigang harbor is built on a river carrying a small amount of sediment.By means of physical model tests,the sediment transport law for the lock approach of Guigang harbor,the mechanism and properties of sediment accumulation are analysed,and the amount and the largest thickness of sediment accumulation in the area of the approach gateway in three kinds of typical years are obtained.It is indicated that in canalization of a river which even carries a small quantity of sediment,sediment accumulation in the lock approach should not be overlooked;and to eliminateit relevant measures must be taken. |

| Keywords: | loek approach eddying water density current sediment accumulation suspended load |
