摘要
本文对风干的红砂岩粗粒土及饱水红砂岩粗粒土路堤填料进行了CBR试验、耐崩解试验、压缩试验和剪切试验。试验结果说明水对红砂岩粗粒土的CBR值影响明显,但是其加州承载比均大于规范要求。红砂岩粗粒土适合作为高等级公路的路基填料,但是在实际工程应用时要注意水对红砂岩粗粒土软化的影响。
The CBR test, slake durability test, compressing test and shearing test of the dry and wet redstone granular soil samples were respectively carried out in this paper. The CBR test data showed the water factor has obvious effects on redstone granular soil＇s CBR value, but the CBR values were larger than the referenced CBR value in codes, which suggest that the redstone granular soil was a good kind of embankment fillings. While, tests showed that water can soften the redstone granular soil and we should consider this harmful factor in the embankment engingeering practice.
