公路沥青路面质量通病及其预控浅析摘要步入21世纪以来，我国的经济发展突飞猛进，我国基础设施建设正以前所未有的规模在全国展开，同时质量问题越来越成为人们关注的焦点，近年来频繁出现的一些质量事故，如路基沉陷、大坝决堤、房屋倒毁等等，直接关系到人民群众生命财产安全，引起国家有关部门的高度重视。因此，我们必须重视和加强施工现场的工程质量管理，提高工程施工质量。在顶岗实习一年的时间里，我作为北京市2010年疏堵工程六里桥南里站改造工程和西道口过街天桥改造工程的技术员，深有体会的意识到远离“豆腐渣”工程，真正做到对工程、人民群众负责的重要性。倡导建筑人建造出高质量、高科技让人民群众放心的工程。本文就强调沥青路面早期破损日益增多的现象，对路面施工基础技术要求、质量要求、预防措施等做出扼要说明和自我见解。关键词:公路；桥梁；工程质量管理；事故处理Abstract1Sinceentering21stcentury,duetothefastnationaleconomicdevelopment,theinfrastructureconstructionprojectsarebeingimplementedandconductedinanunprecedentedscalenationwideinChina.However,atthesametime,moreandmorepeopleputtheirfocusontheprojectsqualityissue,suchasfoundationsettlement,Damburst,HouseandBuildingcollapse,whichhasstraightsomethingtodowithsafetyofthepeopleandproperty,andfocusedonbytherelevantnationalinstitutions.Therefore,weshouldpayattentiontoandstrengthenthemanagementintermsofprojectqualitycontrol,andimprovethequalitysincerely.Duringtheoneyear’practice,asanengineerintheprojectofDredgingoftheLiuliqiaoBridgeSouthstationandrenovationofover-bridgeinwestopening2010inBeijing,Ireallyrealizedtheimportancethatweshouldkeepfarawayfromthelow-qualityprojectandreallyberesponsibletotheprojectandourpeople,soweadvocatetoconstructtheworksinhighquality,byhightechandtopeople-satisfaction.Thisarticleemphasizedtheissueoftheincreasinginitialdamagedasphaltpavement,anddemonstratedthecriticalandconcisedescriptionintermsofpavementbasictechnicalrequirementandqualitycontrolrequirementandprecautionandprotectionmeasures.KeyWords:road,Bridge,projectqualitycontrol,accidentsettlement目录1绪论...........................................................................................................................122沥青路面早期破损及平整度控制...................................................................22.1沥青路面早期破损及平整度不合格的原因.........................................................22.2预防早期破坏及平整度的措施.............................................................................23软土地基超限沉陷...............................................................................................93.1软土地基超限沉陷的危害.....................................................................................93.2软土地基沉陷需加固的情况.................................................................................93.3处理软土地基超限沉陷的措施及原理.................................................................94其他常见的病害及处理方法...........................................................................104.1混凝土结构物表面不光滑外观不美观应采用以下方法进行预防...................114.2桥梁伸缩缝和桥头跳车.......................................................................................114.3预应力结构孔道压浆不实...................................................................................114.4水泥路面断板、开裂...........................................................................................125结语..........................
