三峡枢纽工程施工规模巨大，施工强度高，技术复杂。针对施工期通航、长江截流、高强度土石方和混凝土施工、三期碾压混凝土围堰和双线五级船闸等诸多施工技术难题，工程采用了“三期导流、明渠通航、围堰发电”施工方案。文章重点介绍了施工导流、土石方和混凝土工程施工实践与主要创新成果。

The construction of Three Gorges Project (TGP) is characterized by large construction scale, high construction intensity and complexity in technology. In view of various technical difficulties such as navigation in construction period,Changjiang river closures, high intensity concrete and earth rock construction,roller compacted concrete (RCC) cofferdam in 3-stage III and double line five step ship lock,the general arrangement of the project construction is as follows:construction in 3-stage,navigation with diversion channel and power generation under cofferdam project.The practice and innovation achievements in river diversion during construction as well as earth rock and concrete construction were presented emphatically.
