Abstract滑坡影响因素的选取是危险度区划研究的基础和核心工作,坡体结构因素是反映区域滑坡稳定性的重要指标。以三峡库区重庆市万州区为例,介绍了利用滑坡数据库中地层产状和坡向基础数据,通过GIS空间插值和空间分析得到区域滑坡坡体结构因子图层的方法;并通过概率统计分析和模拟,确定坡体结构因子连续概率赋值模型,得到区域连续的概率值域坡体结构图层,从而进一步完善滑坡危险度区划指标体系和定量化程度。
Other AbstractLandslides are influenced by many factors that may be subgrouped into external factors and internal factors, and structure of slope is one of the most important internal conditions. In this paper, the method of providing slope structure map on regional scale landslide research is presented by GIS spatial analysis tools and stratum attitude and aspect map. By studying how slope structure contribute to landslide occurrence, the method of probability to assign continuous value to slope structure map is presented. The new analysis method is offered for formation research of regional landslide. By using this method, the shortage of traditional methods is overcomed, and the analysis result will be more reliable.
