针对少沙河流上船闸引航道泥沙淤积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门区最大淤积厚度．研究表明，少沙河流上的船闸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
In view of the small amount of research data on sediment deposition in the navigation channel of the shiplock at the Shaoxing River, a physical model test was used to study the law of water and sediment movement in the guide channel of the Guizha junction and to analyze the mechanism and characteristics of the sedimentation in the navigation channel. The sediment silt volume of the pilot channel and the maximum siltation thickness of the hatchway at the approach channel of the three characteristic years were measured. The research shows that the siltation of the navigation channel of the lock on the Shaoxing River is still a problem that can not be neglected. In the construction, the corresponding silt removal measures must be considered
