《河南水利与南水北调》2023年第2期百家谭某大型输水渠道应急抢险措施及效果分析陈妍1，许伟伟2，刘晓东3（1.河南黄河水文勘测设计院，河南郑州450008；2.河南省人民胜利渠管理局，河南新乡453100；3.河南省水利第二工程局，河南郑州450008）摘要：某大型渠道输水总干渠受短时间强降雨影响，局部渠段左侧一级马道出现裂缝险情，后发展至马道混凝土路面塌陷，衬砌板拱起破坏等。鉴于以上情况，疑似马道下部换填土体滑移，且有进一步发展的趋势，渠道边坡面临重大险情，需进行应急抢险处理。险情发生后，根据现场情况，分析了破坏原因，提出了综合应急抢险措施，采取了降水、压重以及通过控制闸抬升渠道内水位等方法，并结合现场布置的监测点分析了应急抢险措施的处理效果，对类似工程应急抢险有一定指导意义。关键词：大型输水渠道；应急抢险；措施及效果中图分类号：TV85文献标识码：A文章编号：1673-8853（2023）02-0103-03EmergencyMeasuresandEffectAnalysisofalarge-scaleWaterConveyanceChannelCHENYan1,XUWeiwei2,LIUXiaodong3（1.HenanYellowRiverHydrologicSurveyandDesignInstitute,Zhengzhou450008,China；2.People’sVictoryCanalAdministrationofHenanProvince,Xinxiang453100,China；3.HenanSecondWaterConservancyBureau,Zhengzhou450008,China）Abstract：Themainchannelofalargecanalwasaffectedbytheshorttimeofheavyrainfall,andpartofthefirstgradebridlewayontheleftsideofthechannelappearedcracks.Later,thecrackdevelopedtobridleroadconcretepavementcollapse,liningplatefailure,etc.Inviewoftheabovementionedsituation,itissuspectedthatthelowerreplacementsoilbodywasslipping,andtherewasatrendoffurtherdevelopment.Thechannelslopewasfacingamajordanger,andemergencytreatmentwasneeded.Afterthedangeroussituationoccurred,accordingtothesituationonthespot,thecausesofdamagewereanalyzed,thecomprehensiveemergencymeasureswereputforward.Themethodsofdewatering,pressingandraisingwaterlevelinthechannelwereadopted.Combinedwiththemonitoringpointsarrangedinthefield,thetreatmenteffectofemergencymeasureswasanalyzed,whichhascertainguidingsignificanceforsimilarprojectsemergencyrescue.Keywords：large-scalewaterconveyancechannel;emergencyrescue;measuresandeffects0引言2016年7月9日，豫北...
