| 摘 要： | 三眼峪“8．8”特大泥石流属典型的沟谷型泥石流，整个沟域具有明显的形成区、流通区及堆积区。通过野外调查，竹塔沟-桥子沟以上的大、小眼峪上游沟脑为雨洪产流汇流区域，产流区与罐子坪-峪支沟一线之间为主要的固体物源区，大、小眼峪口至三眼峪口之间以过流为主，峪口至白龙江之间为堆积区。通过分析三眼峪流域分区特征和泥石流在不同分区的沿程冲淤变化，以期为建立三眼峪泥石流监测预警体系提供依据。

| Abstract: | 8.8 extremely big debris flow in Sanyanyu belongs to typical gully debris flow with obvious forming zone,transportation zone and accumulation zone.Based on site investigation,it is found that the gully head of upstream Dayanyu and Xiaoyanyu,situating at the up streams of Zhuta gully and Qiaozi gully,is the forming and accumulation zone of flood.It is also noted that the area between the forming zone and Guanziping-Yuzhi gully is the main solid source area.Area between Dayanyu-Xiaoyanyu and Sanyanyu is domin... |
