道路翻浆的原因及处理措施

摘要--I摘要道路翻浆，是指路段上因土的特性、季节性水分的运移及气候的影响，而引发的弹簧状态。道路翻浆现象是处在一年四季之中的，水分因为不同季节而产生不同的运动状态，在冬季冻胀与春季融化之后，对路面产生弹簧、鼓包、泥浆、裂缝等现象。在我国，尤其以北方地区与西藏等地，因为受到季节气候，以及冻土的影响，道路翻浆现象比较严重，这对这些地区的交通运输造成了巨大损失。目前，在国内外对于冻土及道路翻浆的研究的基础上，我国已经在冻土领域迈出了一大步，但是道路翻浆的形成机理机理与防治、养护措施，仍是我们日后对于北方及西藏地区公路研究的主要方向。笔者在国内外研究成果的基础上，对道路翻浆的原因及主要形成条件进行简要的分析，并提出道路翻浆的养护、防治措施。关键词道路翻浆；翻浆机理；防治养护Abstract--IIAbstractFrothingreferstoaffectthecharacteristicsofthesoilontheroadduetoseasonalmoisturemigrationandclimatecausedbyspringstate.Frothingphenomenonthroughouttheyearamongthewaterbecauseofthedifferentseasonshavedifferentstateofmotion,inthespringafterthewinterfrostandthawofpavementspring,thephenomenonofdrumkits,mudcracksin.Inourcountry,especiallyinthenorthernregionandTibet,becauseofseasonalclimateandpermafrosteffectsofroadfrostboilingphenomenonisquiteserious,whichoftheseregionstransportationcausedhugelosses.Atpresent,athomeandabroadforstudyofpermafrostandFrothingonthebasisofpermafrostareasinChinahastakenabigstep,butthemechanismoftheformationmechanismFrothingandcontrol,conservationmeasures,wearestillinthefutureforthenorthernandthemaindirectionofresearchinTibethighway.Theauthoronthebasisofdomesticandforeignresearchresults,forthereasonsandthemainroadFrothingbriefanalysisoftheformationconditionsandproposedconservation,preventionofroadFrothing.KeywordsFrothing;Frothingmechanism;PreventionofconservationAbstract--I目录摘要...........................................................................................................................................IAbstract..................................................................................................................................II1绪论.......................................................................................................................................11.1研究的目的及意义...........................................................................................................11.2研究对象...........................................................................................................................11.2.1对翻浆土体进行理论性研究........................................................................................11.2.2对道路翻浆机理的研究................................................................................................22道路翻浆形成的原因...........................................................................................................32.1道路翻浆的概述...............................................................................................................32.1.1道路翻浆产生的主要地区............................................................................................32.1.2道路翻浆的形成过程....................................................................................................32.2形成道路翻浆的原因.......................................................................................................42.2.1水的影响........................................................................................................................42.2.2土质的影响....................................................................................................................42.2.3气候的影响....................................................................................................................42.2.4车辆荷载的影响............................................................................................................42.3道路翻浆带来的危害.......................................................................................................43道路翻浆的分类...................................................................................................................63.1水文地质类翻浆...............................................................................................................63.2是温差类翻浆...................................................................................................................63.3表面类翻浆.......................................................................................................................63.4混合类翻浆.......................................................................................................................64道路翻浆的施工与处理.......................................................................................................74.1翻浆地区的施工...............................................................................................................74.1.1排水................................................................................................................................74.1.2路堤................................................................................................................................74.1.3路堑................................................................................................................................74.2道路翻浆的处理方法.......................................................................................................84.2.1翻浆的防治原则............................................................................................................84.2.2翻浆的处理方法....................
