摘要： 观音滩河段河工模型试验研究是在结合三峡工程175m方案蓄水期变动回水区特点和库区航运的发展要求基础上进行的．本文论述了观音滩河段滩险特征，碍航原因及早期整治工程概况，模型设计情况．同时，通过无方案、原方案及修改方案的试验成果分析及方案综合对比，提出了整治该河段整治的最佳工程方案，为三峡工程建成后该河段通过万吨级船队的整治工程设计提供了可靠的依据，也对进一步深入研究洪水急流滩不同滩型的碍航机理及对应的整治工程措施奠定了基础．

Abstract: The sutdy deals with the river regulation and shipping in the rear reach of the Three Gorges Project.The report exhaustively expounds the natural stream regime, the original design schemes and the modified one. Here furnishes comprehensively the gradient of water surface, velocity, flow patterns, boat-model test, regulation measures, project quantity and so on. Based on the comparison with different schemes and analysis of test data, an optimum regulation scheme is recommended, which gives a reliable basis for regulating the reach, so that the tenthousand- ton fleet can sail up to Chongqing. It is also useful to further investigations and thorough researches on the typical torrent rapids.

Key words: river model test, rapid characteristics, waterway regulation engineering
