摘　　要：云南省地处我国西南山区,地形复杂,斜坡地质灾害频发、多发。省内油气管道分布密集,近年来投产的长输油气管道主要有西南成品油管道、中缅油气管道、百色至昆明成品油管道等。油气管道的建设、运营和管理面临着不同类型山地灾害的挑战。本文基于2017年9月14日云南昆明市水节箐右岸管道泥石流现场调查,分析了高位溃决型坡面泥石流灾害的启动、演化、成灾基本特征以及油气管道防治对策,研究成果对推动西南山区长输油气管道沿线泥石流灾害工程治理具有积极意义。Yunnan Province is in the southwest mountainous area of China,where slope debris flows are fully developed and clustered along slopes,posing great threats to the operating safety of oil and gas pipelines.The long-distance oil and gas pipelines,mainly consisted of the southwest oil product pipeline,the Sino-Myanmar oil and gas pipeline,and Baise to Kunming s refined oil pipelines,etc.,had been installed in southwestern China in recent years.Their construction,operation and management are suffering the damages due to types of mountain disasters haunting the relieffed region.Based on field investigations,a sudden and severe slope debris flow on the right bank of the ShuiJiejing of Kunming City,Yunnan Province on September 14,2017,was carefully investigated by jointly examining of geological and hydrometeorological data.The initiation,evolution and formation of high-position catastrophe-prone slope debris flow were performed for a case study.And the basic characteristics of slope debris flows and its prevention and control measures were concluded.This investigation would provide us an engineered insight into the understanding of the damage pattern of slope debris flow on oil and gas pipelines and enlighten the management of mountain pipeline geohazards.
