香溪河河水与八字门滑坡粘性土物理化学作用的试验研究的开题报告【摘要】本文旨在研究香溪河河水与八字门滑坡粘性土的物理化学作用，以探究河水对滑坡稳定性的影响。通过建立试验模型，对不同浓度的香溪河河水与八字门滑坡粘性土进行接触角测量、电导率、pH值等性质测试，以及流变学测试和扫描电镜观察等手段，分析河水对滑坡土体亲水性的影响及其对土体物理化学性质的改变，探究河水对滑坡稳定性的影响规律。结果表明，香溪河河水中的离子和溶解物质会改变滑坡土体的表面电荷分布和水分合力状态，进而影响其物理力学性质和稳定性。本文的研究成果为香溪河滑坡的稳定性评估及防治提供了一定的理论和实验依据。【关键词】香溪河；滑坡；物理化学作用；稳定性评估【Abstract】ThepurposeofthispaperistostudythephysicalandchemicaleffectsofXiangxiRiverwateronthecohesivesoiloftheBazimenlandslide,inordertoexploretheimpactofriverwateronthestabilityofthelandslide.Byestablishingexperimentalmodels,differentconcentrationsofXiangxiRiverwaterandthecohesivesoiloftheBazimenlandslideweretestedforcontactangle,electricalconductivity,pHvalueandotherproperties,aswellasrheologyandscanningelectronmicroscopyobservation,toanalyzethehydrophilicityofthelandslidesoilaffectedbyriverwateranditsphysicalandchemicalpropertieschanges,andexploretherulesoftheimpactofriverwateronthestabilityofthelandslide.TheresultsshowthattheionsanddissolvedsubstancesinXiangxiRiverwaterwillchangethesurfacechargedistributionandwatercohesionstateofthelandslidesoil,therebyaffectingitsphysicalandmechanicalpropertiesandstability.TheresearchresultsofthispaperprovideatheoreticalandexperimentalbasisforthestabilityassessmentandpreventionoftheXiangxiRiverlandslide.【Keywords】XiangxiRiver;landslide;physicalandchemicaleffects;stabilityassessment
