摘　　要：为了进一步增强长江上游航道整治建筑物的稳定性和牢固性,减少以后工程的维护量,根据长江上游航道河床、水流特点,通过分析长江上游宜宾至重庆河段内整治建筑物的破坏形式以及破坏机理,提出了4种坝体新结构,以长江上游宜宾至重庆河段建设工程为依托,进行了新结构试验性应用,应用结果表明,4种坝体新结构整体稳定,较好的维持了整治效果,为其他山区河流的航道整治提供了技术借鉴。In order to further enhance the stability of regulating structures in the upper Yangtze River,and to reduce the quantity of future engineering maintenance,the failure mode and mechanism of regulating structures in Yibin-Chongqing section in the upper Yangtze River were studied in this paper.According to the characteristics of river bed and flow of the navigation channel in the upper reach of the Yangtze River,four new types of dike body structures were presented,and in the waterway construction project of Yibin-Chongqing section,the dike body structures were applied and achieved good results,which can provide references for the improvement of navigation channel in mountain rivers.
