| Abstract: | 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. |
