摘要
本文以五峰土家族自治县傅家堰乡桂竹溪滑坡为研究对象,对其地质灾害变形特征及稳定性进行了详细分析。桂竹溪滑坡变形特征明显,主要表现为坍滑、地裂缝及房屋变形。通过工程地质勘察、现场调查、GNSS监测等手段,揭示了滑坡的形态、物质组成与结构特征,并采用单参数反演法对滑带土的抗剪强度参数进行反演分析,最后通过传递系数法对其稳定性进行了定量评价。结果表明,滑坡在天然状态下基本稳定,而在暴雨工况下处于欠稳定状态。再结合滑坡的变形特征和稳定性分析结果,提出了抗滑桩支挡防护、设置排水沟及监测措施等综合治理建议,以期为类似地质灾害的防治提供参考。
This article takes the Guizhuxi landslide in Fujiayan Township,Wufeng Tujia Autonomous County as the research object,and conducts a detailed analysis of its geological hazard deformation characteristics and stability.The deformation characteristics of the Guizhuxi landslide are obvious,mainly manifested as collapse,ground fissures,and house deformation.Through engineering geological survey,on-site investigation,GNSS monitoring and other methods,the morphology,material composition and structural characteristics of the landslide were revealed.The single parameter inversion method was used to invert and analyze the shear strength parameters of the sliding zone soil.Finally,the stability was quantitatively evaluated through the transfer coefficient method.The results show that the landslide is basically stable in the natural state,but under stable in the rainstorm condition.Based on the deformation characteristics and stability analysis results of landslides,comprehensive treatment suggestions such as anti slip pile support and protection,setting up drainage ditches,and monitoring measures are proposed to provide reference for the prevention and control of similar geological disasters.
