| 摘 要： | 由于工程老化，年久失修，北墅水库输水暗渠墙体多处发生位移破坏，严重影响工程的正常使用。通过对输水暗渠墙体破坏区受力状态的初步分析，找出了输水暗渠破坏原因，得出了破坏区墙体与拱座是分离的、直墙顶不承受拱荷载作用、在墙背回填料和较高外水压力作用墙体不满足抗倾安全要求而破坏的结论，提出了衬砌加固处理措施。

| Abstract: | In Beishu Reservoir,the displacement destruction appears at the underground conveyance canal because of ageing without repair.It influences the normal operation of the reservoir.Through the preliminary analysis of stressing conditions in the destroyed wall,the destructive cause is discovered along the underground conveyance canal.The wall in the destructive area is separated from the arch abutment and the vertical wall top doesn't bear the loading from the arch.The wall body cannot meet the demand of safety against overturning under the action of backfill and higher external water pressure.In the paper,the authors have put forward the measures of consolidation treatment in liner. |
