随东西部铁路建设的快速贯通,高原山区铁路的设计时速不断提高,其铁路建设中路基设计与施工方面的要求也随之提高。路基本体、基床是构成高速铁路路堤重要组成部分,其中铁路基床分为基床表层、基床底层两部分。作为高速铁路轨道的直接基础,基床表层是影响路基建设的重要部分。就铁路路基填料的施工及检测进行统计分析,以供参考。
With the rapid development of the railway construction between the east and the west, the design speed of the railway in the plateau and mountainous region has been continuously increased, and the requirements for the design and construction of the subgrade in railway construction have also been raised. Subgrade and foundation bed constitute an important part of high-speed railway embankment, in which the railway bed is divided into two parts: the basement bed and the basement bed. As a direct basis for high-speed railway tracks, the bed surface is an important part of the subgrade construction. On the railway subgrade filler construction and testing for statistical analysis for reference.
