摘　　要：巴坡村位于云南省怒江州贡山县,区内岩石节理裂隙发育、风化强烈,沟壑陡峭,泥石流爆发风险较高。本研究通过现场勘察收集数据,分析巴坡村泥石流发育特征,运用RAMMS软件模拟不同降雨频率下泥石流运动堆积过程,并基于模拟参数进行危险性评价。结果显示,降雨冲刷使沟道两岸岩土体滑坡,泥石流在沟口淤积;随着降雨强度增加,其运动特性和影响范围增大,沟口堆积区中高危险区面积与占比上升,对居民区危害加大。该成果为巴坡村泥石流防治提供理论依据,也为相似地区泥石流预测和治理提供参考。Bapo Village is located in Gongshan County,Nujiang Prefecture,Yunnan Province.In the area,rock joints and crevices are developed,weathering is strong,ravines are steep,and the risk of debris flow is high.In this study,the development characteristics of debris flow in Babo village were analyzed by collecting data from field investigation.RAMMS software was used to simulate the process of debris flow movement and accumulation under different rainfall frequencies,and risk assessment was carried out based on the simulated parameters.The results show that the rain erosion causes the rock and soil mass to slide and the debris flow to accumulate in the mouth of the gully.With the increase of rainfall intensity,its movement characteristics and influence range increased,and the area and proportion of high risk areas in the gully mouth accumulation area increased,and the harm to residential areas increased.The results provide a theoretical basis for debris flow prevention and control in Bapo village,and also provide a reference for debris flow prediction and control in similar areas.
