摘要
三峡工程是中国 ,也是世界最大的水利综合利用枢纽。 1986～ 1989年 ,全国 412位专家参加的三峡工程重新论证 ,为工程开工建设奠定了基础。三峡工程 7年多以来建设进展顺利 ,工程施工按批准的总进度计划实施 ,工程投资控制在审定的初步设计总概算范围内 ,施工质量良好 ,满足设计要求。重新论证的若干重要结论得到了初步验证 ,大江截流、深水围堰、永久船闸高陡边坡开挖稳定 ,特高强度混凝土浇筑施工等一系列重大科技难题得到克服 。
The Three Gorges Project is the largest multi\|purpose hydro\|development project ever built in China and so in the world.The re\|verification on TGP undertaken by 412 Chinese experts from 1986 to 1989,laid the foundation for the execution of the project construction.Since 1993,the construction has been commenced and proceeded smoothly according to the approved general schedule.The project investment is well controlled within the approved estimates of the preliminary design.The quality of the work already completed is satisfactory to the design requirements.Several important conclusions drawn from the re\|verification have been proved preliminarily to be correct.And a series of major technical challenges,such as river closure of the grand channel,the construction of the deen water cofferdam,the excavation stability of the permanent ship lock with high slope,and the extremely high intensive concrete placement,have been met.The practice has fully proved the necessity and correctness of the previous scientific verification.
