摘　　要：川江斗笠子滩为枯水急流滩险。在分析斗笠子滩历史整治得失、碍航特性与演变规律基础上,结合河工模型试验研究,提出上扩下抬的治理思路,采取疏炸与筑坝的工程措施进行整治。工程实施后,碍航险情消失,整治效果良好。Doulizi beach is the dry rapids in Chuanjiang River. Based on the analysis of historical regulation＇s effect, navigation-obstructing characteristics and evolution law, combining physical model study, the article proposes the regulation plan of dredging and blasting at upstream and constructing dike at downstream. After implementation of the plan, the danger of navigation-obstruction disappeared, and it reavealed that the regulation effect is satisfactory.
