三峡库区黄土坡滑坡降雨入渗作用过程的开题报告【摘要】本文研究了三峡库区黄土坡滑坡降雨入渗作用过程，选取了三峡库区某黄土坡进行了现场实验，采集了降雨量、地面径流量、土壤含水量等数据，并对数据进行了分析。结果表明，降雨量对滑坡稳定性影响较大，且滑坡区域土壤持水能力较低，容易产生地面径流。同时，土壤含水量与滑坡稳定性呈现一定的相关性，当土壤含水量达到一定阈值时会导致滑坡发生。因此，在管理黄土坡时，需要密切关注降雨情况，加强水土保持工作，提高黄土坡的稳定性。【关键词】三峡库区；黄土坡滑坡；降雨入渗；土壤含水量；稳定性【Abstract】ThispaperstudiestheprocessofrainfallinfiltrationontheloessslopelandslideintheThreeGorgesreservoirarea.FieldexperimentswereconductedonaloessslopeintheThreeGorgesreservoirarea,anddatasuchasrainfallamount,surfacerunoff,andsoilmoisturecontentwerecollectedandanalyzed.Theresultsshowthatrainfallhasasignificantimpactonlandslidestability,andthesoilwaterholdingcapacityinthelandslideareaislow,whichispronetosurfacerunoff.Atthesametime,thereisacertaincorrelationbetweensoilmoisturecontentandlandslidestability.Whenthesoilmoisturecontentreachesacertainthreshold,landslideswilloccur.Therefore,inmanagingloessslopes,weneedtocloselymonitortherainfallsituation,strengthenwaterandsoilconservationwork,andimprovethestabilityofloessslopes.【KeyWords】ThreeGorgesreservoirarea;loessslopelandslide;rainfallinfiltration;soilmoisturecontent;stability
