摘　　要：为减少青海省化隆县德恒隆乡牙曲滩村山尕滩社泥石流频发造成的地质灾害,在研究区开展了一定工作量的地形测量、工程地质测绘、山地工程、钻探工程以及现场试验等工作的基础上,从地形地貌、气象、物源等方面分析了区内泥石流的形成条件、泥石流的基本特征及控制因素。综合区内地质环境背景、泥石流形成条件、运动堆积特点及其对区内居民、村道的危害特征,经详细勘查工作提出了“拦挡坝+排导渠”工程治理措施,改变了以往该区泥石流治理措施的盲目性和随意性,从而减少泥石流灾害的发生。对山尕滩社泥石流的形成条件及其治理进行分析研究具有重要意义。In order to reduce geological disasters caused by frequent mudslides in Shangatanshe,Yaqutan Village,Dehenglong Township,Hualong County,Qinghai Province,a certain amount of work such as topographic surveying,engineering geological surveying and mapping,mountain engineering,drilling engineering and field tests was carried out in the research area.On this basis,the formation conditions of debris flows in the area,the basic characteristics and controlling factors of debris flows were analyzed from the aspects of topography,meteorology,material sources,etc.Based on the geological environment background of the area,debris flow formation conditions,movement and accumulation characteristics,and the hazard characteristics to residents and village roads in the area,after detailed investigation work,the engineering management measures of“retaining dam+drainage channel”were proposed,which changed the blindness and randomness of debris flow control measures in the past at this area,reducing the occurrence of debris flow disasters.It is of great significance to analyze and study the formation conditions and management of Shangatanshe debris flow.
