三峡施工期葛洲坝通航水位工程措施研究

On Construction Measures for Navigable Depth of Gezhouba Dam During Construction of the Three-Gorges Project

通过葛洲坝下游宜昌河段的水文资料分析 ,提出了三峡工程施工期间 ,葛洲坝三江航道将面临断航的威胁 ;在定床实体模型上 ,进行了整治工程方案试验研究 。

From the analysis of hydrolic data of Yichang Reach at downstrean water of Gezhouba Dam,it's consi dered that navigation in Sanjiang Channel will be influenced during the constrution of the three Gorge project.Therefore,test study on the regulation scheme is performed on the fixed bed model and the problem of navigable depth during the construction of the Three Gorge Project will be basically solved by the regulation scheme proposed in the paper.
