摘要
三峡通航建筑物上游隔流堤工程位于大坝上游引航道右侧 ,起到工程汛期低水位运行时将引航道与长江主流隔开 ,减少引航道淤积和改善通航水流条件的作用。其中跨临时船闸上游引航道段 (简称深槽段 )施工项目 2 0 0 2年 8月 15日开工 ,是三峡工程 2 0 0 3年蓄水、通航、发电 3大目标实现的控制性项目之一。对工程所存在的影响工期的填筑、料场开挖。
The upstream separation levee of TGP's permanent shiplock is located at right side of approach channel, functioning as separating the approach channel from the main stream of the Yangtze river in the period of low water level operation of the project in flood season to reduce the sedimentation in the navigation channel and improve the navigation flow condition, in which, the section of upstream approach channel across the temporary shiplock (brief as deep channel section) started construction on August 15, 2002 and it is a control project for the realization of water impoundment, navigation operation, power generation of TGP this year. The resolving schemes on backfilling, material field excavation, concrete placement etc.,which influence on construction period, are presented.
