红砂岩崩解特性及其路堤填筑技术研究

结合某高速公路大型模拟试验路堤及实体工程试验路段试验研究,从研究红砂岩的化学成分与结构特征入手,深入探讨了红砂岩崩解试验方法及其崩解机理与特性,从而提出了红砂岩的有效工程分类方法,并在此基础上,深入研究了红砂岩作为路用材料的路堤填筑技术,进而确定出红砂岩路基填筑的合理施工工艺,并提出了相应合理的路基填筑质量控制标准及其检测方法,为红砂岩地区高速公路路堤填筑提供了可靠的技术保证。

Study of the disintegration character of red sandstone and the construction techniques of red sandstone embankment

Combined with study on the test of simulating embankment and practical engineering of one highway, the mechanism, characters and the test method of disintegration of red sandstone had deeply been discussed and the effective classified method of red sandstone in engineering had been brought forward. Moreover, the techniques of embankment filling using red sandstone as embankment material had been researched and valid construction techniques of red sandstone embankment had been established, and the rational quality control standards and the detective method of embankment had been put forward, authors had provided a reliable technique which pledge for filling of embankment of highway in red sandstone regions.
