Study on Width Prediction of Sliding Bank Collapse of Reservoir Surface Soil in Mountainous Area Based on GIS

中文摘要英文摘要

目前预测水库塌岸的已有方法都有一定的适用范围,且预测结果相差悬殊,大都不能满足地质条件复杂多变的高山峡谷水库塌岸预测的需求。山区水库表土滑移型塌岸宽度的预测,就是找到塌岸所在滑坡的空间范围,尤其是滑移体的后缘边界,因此可基于 GIS的三维模型对 DEM 栅格数据进行处理,划分边坡单元,以边坡单元为研究对象,采用Monte Carlo模拟搜索方法确定三维最危险滑动面,进而确定塌岸有关参数、预测塌岸宽度等。经实例分析验证,该方法可用于预测山区水库表土…查看全部>>

At present,the existing means of reservoir bank collapse prediction has certain scope and the predicted results vary dramatically. Mostly,they can′t meet the demand of high mountain gorge with complicated geological conditions reservoir bank collapse prediction. The prediction of width of bank collapse is to find the space of the landslide,especially the rear of the sliding mass boundary. So the 3D model based on GIS used DEM grid data to divide the slope un…查看全部>>
