摘　　要：渠化航道船闸锚地布置中需考虑枢纽运行调度和采砂的影响。针对这一情况,讨论了水流条件复杂、河床覆盖层薄、锚地选址困难等设计难题。以湘江大源渡船闸和株洲船闸锚地布置为例,提出自抛锚为主、丁靠为辅,全年锚地和枯水锚地相结合的锚地布置方式。通过实船调查,提出了自抛锚地的最小覆盖层厚度,并提出中洪水专用自抛锚地和枯水专用丁靠锚地相结合的方案,解决了船闸下游自抛锚地覆盖层薄、沿岸丁靠锚地造价高昂的难题。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.
