摘要
树坪滑坡失稳产生持续剧烈变形。为解决滑坡现有变形监测点数量稀少、分布不均,监测数据无法反映整体变形情况的实际问题,引入张力样条(Tension Spline)插值方法,借助ArcGIS平台分析计算出树坪滑坡变形场。统计分析了滑坡空间插值变形在不同高程、坡度中的分布规律。结果表明,坡度越大、高程越小树坪滑坡大变形区域分布越广。本文可为深入研究滑坡变形的空间插值方法提供参考。
The instability of Shuping landslide resulted in continuous severe deformation.In order to solve the problem that the existing monitoring points are few and unevenly distributed,and the monitoring data cannot reflect the overall deformation,the Tension Spline interpolation method is introduced by ArcGIS to obtain the deformation field of Shuping landslide.The distribution law of spatial interpolation deformation in different elevation and slope is analyzed statistically.The results show that the larger the slope,the higher the elevation,the wider the distribution of the landslide deformation area.This paper can provide a reference for studying the spatial interpolation method of landslide deformation.
