摘　　要：以甘肃省泾川段油气管道管周原状黄土与回填为研究对象,通过整理资料、激光粒度仪试验分析、线性规划等方法对管周黄土的粒度成分进行了系统的研究,对黄土地区油气管道工程的设计、施工与灾害防治有重要的参考意义。Taking a original loess and backfilling of oil and gas pipelines in the Jingchuan section of Gansu Province as the research object,the grain size components of the tube-soil loess are systematically studied by means of collation data,laser particle size analyzer test and linear programming,the study has the important guiding significance for the engineering design,construction and disaster prevention of the oil and gas pipelines in the loess area.
