摘　　要：针对宜昌市东风渠蜘蛛洞支渠U型薄壳渡槽运行中存在的安全问题,从渡槽基础、支撑、槽身结构及进出口建筑物四个部分开展稳定性分析,并对补强加固措施进行研究。研究结果表明渡槽安全问题主要受早期施工条件、设计缺陷和环境因素影响,局部加固措施无法从根本解决整体结构的安全稳定问题,面对工程质量无法满足设计标准的现状,安全问题严重的渡槽建议降等运行并拆除重建。In view of the safety problems existing in the operation of U-shaped thin-shell aqueduct in Shiidaidong Branch of Dongfeng Canal in Yichang City,the stability analysis is carried out from four parts of aqueduct foundation,support,body structure and entrance and exit building,the reinforcement measures are studied.The results show that the safety problems of aqueduct are mainly affected by early construction conditions,design defects and environmental factors,and the local reinforcement measures cannot fundamentally solve the safety and stability problems of the whole structure.Faced with the current situation that the engineering quality cannot meet the design standards,the aqueduct with serious safety problems is suggested to be run down and rebuilt.
