摘　　要：本文结合国家重点投资项目一包西铁路通道（陕西段）工程实际，根据沙漠地区铁路路基工程设计规范要求、铁路路基施工验收标准并结合经济效益及周边实际填料，对全线不良地质路段提出较为合理的改良试验。通过施工现场的试验得知：采用1：1．5砂土参配方案，虚铺厚度35cm，压实后30cm，最终可松性系数1．15，静压7遍后可达到设计及验标要求，从而分析选取合理的比例及碾压次数满足铁路路基承载力的要求及验标。In this paper, key state investment projects - West Rail Corridor Package （Shaanxi Section） engineer- ing practice, according to deserts railway subgrade engineering design specifications, the railway roadbed construc- tion and acceptance criteria and combination of cost - effectiveness and surrounding the actual packing, right across the board bad geological section presented a more reasonable Improved test. Through the construction site of the tri- als that： The argument with sand 1：1.5 programs, virtual height 35cm, compacted 30cm, eventually loose coeffi- cient 1.15, static pressure seven times can be achieved after the standard design and inspection requirements, to analyze Select the number of reasonable proportions and roiled to meet the requirements of the railway subgrade bearing capacity and the inspection standard.
