随着我国高等级公路建设的迅猛发展,用作路基填筑的材料越来越多,红砂岩就是其中一种较为理想的材料,红砂岩作为路基填料有强度高、稳定性好等优点。文章通过施工实践总结在红砂岩地区修筑高速公路路基过程中遇到的问题和采取的对策,对红砂岩的路基的基本知识及其填筑技术作了简要的论述,并提出尚需进一步研究的问题。 With the rapid development of high-grade highway construction in our country, red sandstone is one of the more ideal materials for embankment filling. As a subgrade filler, red sandstone has the advantages of high strength and good stability. The article summarizes the problems encountered in the process of constructing expressway subgrade in red sandstone area and the countermeasures adopted by construction practice. The basic knowledge of red sandstone subgrade and its filling technology are briefly discussed, and the further research is needed problem.
