摘　　要：三峡通航建筑物上游隔流堤跨临时船闸上游航道段因受临时船闸通航影响,于2003年4月9日至5月31日才能填筑堤身主体,填筑量高达612万m3,计划月填筑施工强度达到20万m3。为保证施工完成后堤身的形体满足设计要求,施工前对施工完成后堤身的沉降量进行了计算估计,施工完成后对坝体沉降进行了观测,对计算和观测结果进行了分析,可供同类工程作一定的参考。Influenced by navigation operation of TGP's temporary shiplock,the embankment construction of upstream separation levee crossing TGP's temporary shiplock was postponed to be carried out in the period of April 9,2005 ～ May 31,2005,the embankment volume reached to 6.12 million m3 and monthly construction intensity was 200 thousand m3.In order to meet the design requirement of the levee body after constructqaion,the settlement volume of the levee body after construction was estimated before construction.After construction,settlement observation of levee body was carried out and the computed and observed results were compared and analyzed.The comparison and analysis results can be referred by other project.
