I题目（中文）：花岗岩残积土边坡破坏规律研究（英文）：StudyonFailureLawofGraniteResidualSoilSlope摘要目前我国对花岗岩残积土边坡破坏规律还没有科学的检测手段，实际上，这类土质比较常见，在日常的施工中可能会误导致花岗岩残积土边坡破坏而造成一系列工程事故。花岗岩地区地质灾害类型主要有滑坡和崩塌两种类型，在实际应用中，影响土质边坡的牢固形态的原因非常复杂。比如说，纹理出现裂缝，以及掺杂杂质，还有结构和水文性质等，都会导致花岗岩的稳定性被破坏。但是最主要的原因应当是花岗岩残积土中空间中的原生与次生结构面的相互关系。本文针对花岗岩残积土边坡破坏，通过对花岗岩残积土的物理特性进行分析研究，阐述花岗岩残积土边坡破坏特征，以广东省梅州市的花岗岩残积土边坡为例，并参考花岗岩残积土的各项相关试验，研究花岗岩残积土在不同降雨条件下的破坏规律，并为设计花岗岩残积土边坡防护提供依据。论文研究对象主要是我国花岗岩覆盖范围较为广泛的地区，结合国内有关参考文献的研究，针对那些地区的建筑工程项目具有指导性，同时也能够解决实际的项目问题，对防治这些地区的边坡破坏有一定的现实意义。关键词:花岗岩；残积土；边坡；稳定性；破坏规律IIAbstractAtpresent,thereisnoscientificdetectionmethodforthefailurelawofgraniteresidualsoilslopeinourcountry.Infact,thiskindofsoilisrelativelycommon,whichmayleadtoaseriesofengineeringaccidentsduetothefailureofgraniteresidualsoilslopeindailyconstruction.Therearemainlytwotypesofgeologicaldisastersingranitearea,landslideandcollapse.Inpracticalapplication,thereasonsthataffectthefirmshapeofsoilslopeareverycomplex.Forexample,theappearanceofcracksinthetexture,aswellasthedopingofimpurities,aswellasthestructuralandhydrologicalproperties,willleadtothedestructionofthestabilityofgranite.Butthemainreasonshouldbetherelationshipbetweenprimaryandsecondarystructuralplanesinthespaceofgraniteresidualsoil.Inthispaper,accordingtothefailureofgraniteresidualsoilslope,throughtheanalysisofthephysicalcharacteristicsofgraniteresidualsoil,thefailurecharacteristicsofgraniteresidualsoilslopeareelaborated.TakingthegraniteresidualsoilslopeinMeizhoucityofGuangdongProvinceasanexample,andreferringtotherelevanttestsofgraniteresidualsoil,thefailurelawofgraniteresidualsoilunderdifferentrainfallconditionsisstudied,Itprovidesabasisforthedesignofgraniteresidualsoilslopeprotection.TheresearchobjectofthispaperismainlytheareaswithawiderangeofgranitecoverageinChina.Combinedwiththeresearchofdomesticreferences,itisinstructivefortheconstructionprojectsinthoseareas,andcanalsosolvetheactualprojectproblems,whichhasacertainpracticalsignificanceforthepreventionandcontrolofslopedamageintheseareas.Keywords：granite;residualsoil;slope;stability;failurelawIII目录1导言..........................................................................................................................11.1研究背景及意义.............................................................................................11.2国内外研究现状.............................................................................................11.2.1花岗岩残积土研究现状...............................................................................11.2.2边坡稳定性分析方法研究现状............................................................32花岗岩残积土的物理性质........................................................................................42.1花岗岩残积土的颗粒组成..............................................................................42.2花岗岩残积土的透水性..............
