高速铁路路堤填筑工艺及质量控制试验研究

High-speed railway embankment filling technology and quality control experiment research

通过试验段现场填筑试验,研究施工工艺参数及施工质量控制要点。在分析孔隙率指标作为评价粗粒土填筑密实度指标的基础上,探讨采用Ev2/Ev1比值作为评定压实质量辅助检测指标的合理性,并提出建议,以期完善铁路路堤填筑工艺。

According to the field filing experiment in experiment section, the author studies the construction technology index and construction quality control points, based on the analysis of taking porosity as index of evaluating coarse grained soil filling compactness, discusses the reasonability of adopting Ev2/Ev1 ratio as evaluating compacting quality auxiliary testing index, and provides suggestions, so as to perform the filling technology of railway embankment.
