摘　　要：针对沙特南北铁路项目在干热高温沙漠地区进行无缝线路上碴整道施工过程中,容易出现"碴包沙"的现象,介绍了上碴整道施工改进技术,分析了沙漠试验段的质量检测方法,为今后类似工程的施工提供实践参考。In light of the phenomenon of ＂ballast-coated sand＂ which is easy to be found during laying ballast and adjusting track for continuously welded rail track in dry desert area with high temperature of Saudi Arabia north-south railway project, this paper introduced the improvement technology of laying ballast and adjusting track, analyzed the method of quality detection in desert test section. It could provide practical reference for construction of similar projects in the future.
