摘　　要：西气东输管道工程需多次穿越沙漠地段 ,根据沙漠地带地形起伏较大、沙丘活动性较强、沙漠抗剪强度小、凝聚力极差等特点 ,通过采取相应的施工机具和措施 ,有效地解决了运管、管沟开挖以及防沙固沙等问题。文章详细介绍了沙漠地带管道施工方法、防沙固沙措施以及施工中的注意事项。The pipeline of West-East Natural Gas Transportation Project passes through desert land several times. Based on characteristics of sand wave hypsography, active sand dune mobility, lower shear strength and poorer coherence and so on in desert land, relevant machines and tools were used and proper methods were carried out. And therefore some problems such as pipe channel trenching, pipeline operation, sand-defense, and sand-solidification etc were solved effectively. The article introduced in details the technologies of pipeline construction in desert land, measures of sand-defense and sand-solidification, as well as attention items should be paid when pipeline in construction.
