三峡库区巴东型大型滑坡特征及休止深度分析

Analysis on Characteristics of Badong-type Large-scale Landslide and Repose Depth in Three Gorges Reservoir Area

调查统计分析表明,巴东县三峡库区干流沿岸有18个方量在100万m3以上的大型滑坡。通过对这些滑坡发育分布及分类特征分析,提出了大型滑坡存在休止边界、休止深度的认识,对解释深层滑移、指导库区滑坡勘察、治理、监测工程施工具有重要意义。

As we known, 18 large-scale landslides are along the mainstream of Three Gorge Reservoir area in Badong County, with the volume above 1 million m3 respectively. In the paper, the distribution and classification feature of these landslides are analyzed to propose the authors＇ understanding on repose boundary and repose depth existing in largescale landslide, which is of great significance in interpreting slide in deep layer, further guiding the investigation, control, supervision and construction of landslide.
