摘要
分析角半沟地形地貌及其泥石流物源条件发现,角半沟上部滑坡积物源丰富,沟域面积大,地形陡峻。暴雨条件容易诱发大规模泥石流。采用频率法计算得到泥石流临界雨量的上下限值范围。
By analyzing the topography and debris source, it＇s found that there are rich sources at the top of the Jiaobangou valley and the valley＇s area is large with steep terrains. Storms are likely to cause large-scale landslides. The frequency method was used to calculate the value range of critical rainfall for debris flows.
