摘　　要：城背嘴滩险是川江泸渝段著名的弯、浅、险滩。根据原型观测资料和模型试验成果,着重从城背嘴河床地形特征、急弯分汉河势以及分流分沙比等方面,探讨了城背嘴滩险的成因。Chengbeizui Waterway is famous for its curve,shallow and hazardousness in the Luzhou-Chongqing Reach of the Yangtze River.Based on prototype measurements and physical model tests,the rapids genesis of Chengbeizui Waterway is discussed mainly from bed configuration,characteristics of sharp-bend with divided flow,and diversion ratio of discharge and sediment.
