2023年第06期总第300期福建建筑FujianArchitecture&ConstructionNo06·2023Vol·300基于模糊综合评价的烂尾楼加固方案比选和优化研究黄星(福建华诚工程研究院有限公司福建泉州362011)摘要:某烂尾楼因施工质量纠纷长期停工后,因重建需要,对其现存质量进行检测,深入分析其承载能力,可知地基基础质量完好,但主体结构的梁、柱、墙等构件有不同程度的损伤,需加固处理。为此,对第3层某框架梁进行分析,结果表明:因原施工质量不佳及后期长时间空置等原因,该框架梁理论计算与软件模拟所得承载性能均不符合设计要求,需进行加固处理;基于层次分析法,确定烂尾楼框架梁加固的各项影响因素指标的权重,选用多级模糊综合评价的方法,对4种加固方案进行综合比选,得出加大框架梁截面面积的方案最合适;为保障加固效果,需对相应的施工步骤进行优化。关键词:烂尾楼;层次分析法;模糊综合评价;加固方案优化中图分类号:TU3文献标识码:A文章编号:1004-6135(2023)06-0089-06OptimizationstudyofreinforcementschemeforrottenbuildingsbasedonfuzzycomprehensiveevaluationHUANGXing(FujianHuachengEngineeringResearchInstituteCo.LTD,Quanzhou362011)Abstract:Arottenbuildinghasbeenhaltedforalongtimeduetoconstructionqualitydisputes.Duetotheneedforreconstruction,itsexist-ingqualitywastestedanditsbearingcapacitywasanalyzedindepth,whichshowsthatitsfoundationqualityisintact,butthebeams,col-umns,wallsandothercomponentsofthemainstructurehavedifferentdegreesofdamageandneedtobereinforced.Thispaperanalyzesaframebeamatthe3rdfloor,andtheresultsshowthatduetothepoorqualityoftheoriginalconstructionandlongvacancyatalaterstage,thebearingperformanceobtainedfromthetheoreticalcalculationandsoftwaresimulationoftheframebeamdoesnotmeetthedesignre-quirementsandneedstobereinforced.Basedonthehierarchicalanalysismethodtodeterminetheweightsoftheindicatorsoftheinfluen-cingfactorsoftheframebeamreinforcementoftherottenbuilding,themulti-levelfuzzycomprehensiveevaluationmethodwaschosentocarryoutcomprehensivemustselectionoffourreinforcementschemes,andtheschemetoincreasethecross-sectionalareaoftheframebeamwasfoundtobethemostsuitable.Toguaranteethereinforcementeffect,thecorrespondingconstructionstepsneedtobeoptim...
