The influence of hub operation scheduling and sand mining should be considered in layout of the ship lock anchorage in canalized waterway.In view of this situation,the design problems such as complicated flow conditions,thin bed cover and difficult anchorage site selection are discussed.Taking the anchorage layout of Dayuandu lock and Zhuzhou lock of Xiangjiang River as an example,this paper puts forward the anchorage layout mode of combining self-anchored anchorage with low-water anchorage throughout the year,with self-anchored anchorage as the main method and dependent anchorage as the auxiliary method.Based on the investigation of the ship,the minimum thickness of the self-anchored area is proposed,and a scheme combining the self-anchored area for flood and the anchorage area for dry water is put forward,which solves the problems of thin overburden of the self-anchored area downstream of the lock and high cost of the anchorage area along the shore.
