南水北调中线工程渠道施工受施工现状条件、工程总体进度要求等因素制约，部分高填方渠段难以满足填方渠道不少于6个月预沉降的时间要求。针对南水北调中线工程典型高填方渠段的实际情况，就填方渠段工后沉降变形对衬砌面板的受力分布、挠曲变形的影响进行了详细的分析，并根据计算成果提出了高填方渠道工后沉降变形控制的建议措施，为渠道充水试验以及正常安全运行提供了技术参考。
南水北調中線工程渠道施工受施工現狀條件、工程總體進度要求等因素製約，部分高填方渠段難以滿足填方渠道不少于6箇月預沉降的時間要求。針對南水北調中線工程典型高填方渠段的實際情況，就填方渠段工後沉降變形對襯砌麵闆的受力分佈、撓麯變形的影響進行瞭詳細的分析，併根據計算成果提齣瞭高填方渠道工後沉降變形控製的建議措施，為渠道充水試驗以及正常安全運行提供瞭技術參攷。

Constrained by the current construction conditions and the requirements for overall construction progress, part of high-filled canal of Middle Route Project of South-to-North Water Diversion is difficult to meet the demand of more than six-month pre-settling time. In view of the actual situation of the typical section of high-filled canal, the impact of settlement deformation after construction on stress distribution, flexural deformation of concrete slab is analyzed in detail. Moreover, the pa-per proposes the control measures of settlement deformation according to the research results, which provides technical reference for the water-filling test and normal safe operation of the high-filled canal.
