Abstract: The water and sediment movement characteristics of Chuanjiang Ｒiver，materials of traditional regulation structure and damage features were analyzed． Based on Tonggutan waterway regulation，the water and sediment movement characteristics in Tonggutan were compared． And the working condition，construction technology and actual effect of accropodes in Tonggutan were also analyzed． And then the conditions and requirements of accropodes’application were put forward． It was appropriate to adopt accropodes to the maintenance of dam in mountainous river with large discharge and quick flow speed． Grid control was used in the construction． The numbers of accropodes installed in per unit area meet the design requirements．

Key words: waterway regulation, Chuanjiang Ｒiver, accropodes

摘要： 通过分析川江水沙运动特性、传统整治建筑物结构材料及损毁特点，以铜鼓滩整治工程为依托，通过对比铜鼓滩 水沙运动特性，分析扭王字块在铜鼓滩的工作条件、施工工艺及取得的实际效果，提出了扭王字块的适用条件及要求。 对于大型山区河流，适宜采用扭王字块对坝体进行护面，施工时可按网格控制，单位面积安装块数要达到设计要求。
