摘要
为研究板岩作为块石路基填料的物理特性,文中以青海省共和至玉树(共玉)高速公路路基块石中的板岩为研究对象,分析了冻融循环作用对其质量、纵波波速和孔隙率的影响.结果表明,随着冻融循环次数的增加,板岩试样的质量、纵波波速均呈减小趋势,而其孔隙率呈增大趋势.以供参考.
Abstract
In order to study the physical properties of slate as a block stone roadbed filler,this paper takes the slate in the roadbed block stone of Gonghe-Yushu(Gongyu)Expressway in Qinghai Province as the research object,and analyzes the effect of freeze-thaw cycle on its quali-ty,longitudinal wave velocity and porosity.The test results show that with the increase of freeze-thaw cycles,the mass and longitudinal wave velocity of slate samples decrease,while the porosity increases.For reference.
