基于InSAR形变的滑面摩擦残余估计与滑坡危险性评价OA北大核心CSTPCD
FRICTION RESIDUAL ESTIMATION AND LANDSLIDE RISK ASSESS-MENT BASED ON INSAR DEFORMATION
传统滑坡灾害危险性评价往往依赖于坡表位移或形变速率等间接特征开展,但较少直接利用滑面自身的物理特征评估滑坡的危险性.在此,本文发展了一种依据滑面摩擦残余的斜坡危险性评价理论与方法,其基本流程为:首先利用In-SAR技术提取滑坡时序变形数据,其次在坡表形变的约束下反演获得斜坡沿滑面的滑移时空演化特征;进一步依据速度摩擦衰减定律计算获得坡体的摩擦系数残余及稳定摩擦系数,并据此分析滑面稳定摩擦系数的时空变化,进而定量评估滑坡的危险性.本文选取西藏山南市…查看全部>>
Traditional landslide hazard assessments often rely on indirect characteristics,such as slope surface dis-placement or deformation rate,but seldom directly utilize the physical properties of the sliding surface itself to as-sess the risk of landslides.In this paper,a slope hazard assessment theory and method based on the residual friction of the sliding surface are developed.The basic process is as follows:Firstly,InSAR technology is used to extract the time…查看全部>>
