高速铁路膨胀土路基基底处理综合施工技术

摘要

以云桂铁路项目为例,介绍了该项目施工段的地质特点,通过对不同路基基底处理工艺的分析,总结出换填配合土工格室垫层施工的膨胀路基基底处理技术,探讨了土工格室施工中的注意事项,保障了路基的施工质量和施工进度.%Taking the Kunming-Nanning rail project as an example, this paper introduced the geological characteristics of the project construction period, through the analysis on different sub-grade base process, summed up the expansive sub-grade base treatment technology of changing coor-dinated the geo-grid cell cushion construction, discussed the matters needing attention in geo-grid cell construction, guaranteed the construction quality and construction schedule of sub-grade.
