板岩路基填料CBR特征及影响因素分析

Study on Influence Factors and Feature of California Bearing Ratio of Slate Subgrade Fillings

软岩在武广铁路客运专线的全线挖方中占60%之多,能否用作路基的填料,对工程费用和环境保护的影响都很大。通过对武广沿线2种典型的板岩填料进行的室内承载比试验,分析了其特征及影响因素,并利用EXCEL“分析工具库”中的“无重复双因素方差分析”工具对各种影响因素的显著性进行了分析,试验结果和分析所得的结论为武广客运专线路基和相关工程的设计与施工提供了参考。

All fronts cubage of cut soft rock along Wu-Guang passenger express railway for special use takes up more than 60 %. And whether it can be used as filling of subgrade, it has enormous affection on construction costs and environmental protection. Through the indoor CBR experiment studies on the two kinds representative slate filling, its characteristic and influencing factor has analyzed, the implement of ＂nonrepeatitive double factor variance analysis＂ in ＂analysis tool storage room＂of EXCEL carries out analysis on the significance of various influencing factor and provides a reference to Wu- Guang railway and relevance project construction.
