摘　　要：针对新疆沙漠地区天然气管道风沙灾害现状,分析了管道沙害的基本形式和致灾机理,并根据风沙流运动的基本特点,经回归推导了新疆沙漠地区不同风速、不同沙丘位置的油气管道覆土风蚀速度与气流流速的相关方程,为油气管道风沙灾害风险评估和安全管理提供了可借鉴的科学依据.For the actualities of wind-sand disaster of the gas transfer pipelines in Xinjiang desert area and based on the analysis of the basic characteristics of wind-sand flow movement,the basic type and mechanism of pipeline＇s wind-sand disaster were summarized.Equation of correlation about the wind speed,the erosive rate of soil covering on the oil and gas transfer pipelines in different dune locations and the speed that airflow moves in the Xinjiang desert area were derived by regression,which has the important significance for the disaster＇s risk evaluation and the security management of the pipelines.
