我国西南山区滑坡泥石流灾害常发，进行区域地质灾害危险性评价的重要指标之一为滑坡泥石流灾害体运移堆积的范围。本文以云南省哀牢山地区水塘镇芭蕉树滑坡泥石流灾害为研究对象，利用Voellmy流体运动模型进行灾害体运移堆积全过程数值模拟反分析，获取数值模拟模型参数。利用反分析得到的模型参数建立与芭蕉树滑坡泥石流所处地质环境条件相似的戛洒镇南恩小学滑坡数值模型，进行滑坡泥石流灾害运移堆积过程模拟分析，模拟结果与野外地质灾害危险性评估结论符合程度较高。

Landslide and debris flow are two common geological hazard types in the South-western mountainous area in China. One of the key factors for hazard assessment of landslides and debris flows is their post-initiation mobility. First, the runout process of Bajiaoshu landslide/debris flow was simulated with the Voellmy frictional model, and parameters were obtained. Then the simulation parameters were used to simulate the runout process of Nan’en School landslide for runout prediction and hazard assessment. The results proved to be consistent with field investigation results and earlier hazard assessment conclusions.
