红砂岩是一种具有特殊物理力学性质的岩体,暴露在自然界表面后,在大气、阳光、特别是雨水的作用下容易崩解。与良好的石质填料相比,红砂岩一般强度低、抗风化能力差、遇水易软化和失水崩解,路基填筑的自稳能力很差,因此未经处治的红砂岩不能直接用作路基填筑。在准备使用红砂岩于路基工程的地区,红砂岩路基的稳定性已成为的工程界急需解决的一大难题。文章主要介绍了红砂岩在路基填筑中的应用技术。
Red sandstone is a kind of rock with special physical and mechanical properties. It is easily disintegrated under the action of the atmosphere, sunshine, especially the rain after being exposed to the surface of nature. Compared with good stone packing, red sandstone is generally low in strength, poor in weathering resistance, easily softened in water and disintegrated in water, and has poor self-stabilizing ability in embankment filling. Therefore, the untreated red sandstone can not be directly used For roadbed filling. In preparation for the use of red sandstone in subgrade projects, the stability of red sandstone subgrade has become an urgent problem to be solved urgently in engineering. The paper introduces the application technology of red sandstone in roadbed filling.
