[目的]研究降雨对滑坡形成和发展的影响、评估滑坡风险,为采取有效的防灾措施提供科学依据.[方法]采用试验的方法,综合评估降雨入渗、土体饱和度、地形等影响因素,分析植被覆盖对减少降雨入渗量的作用.[结果]研究表明,降雨强度和历时对滑坡形成和发展具有重要影响,而植被覆盖可以减少降雨入渗量,对土壤水分的控制起到关键作用.此外,地质特征如土壤类型和坡度也是滑坡发生的重要影响因素.[结论]应加强对降雨诱发滑坡的监测和预警,采取适当的植被措施以控制土壤水分入渗,并重视地质特征对滑坡的影响.
Analysis of Influencing Factors on the Stability of a Landslide Slope in the Three Gorges Reservoir Area
[Purposes]This paper studies the impact of rainfall on the formation and development of land-slides,as well as to assess landslide risks,in order to provide scientific basis for taking effective disaster prevention measures.[Methods]Through experiment,this paper comprehensively evaluates factors such as rainfall infiltration,soil saturation,terrain,and analyzes the role of vegetation coverage in reducing rainfall infiltration.[Findings]Research has shown that rainfall intensity and duration have a significant impact on the formation and development of landslides,while vegetation coverage can reduce rainfall in-filtration and play a key role in controlling soil moisture.In addition,geological characteristics such as soil type and slope are also important influencing factors for landslide occurrence.[Conclusions]In or-der to reduce the impact of landslides on human society,it is necessary to strengthen monitoring and early warning of rainfall induced landslides,take appropriate vegetation measures to control soil moisture infiltration,and pay attention to the impact of geological characteristics on landslides.
