摘    要:通过对兰新铁路第二双线路基试验段工程4个工点路基压实质量K30,Ev2,Evd,孔隙率n4项检测指标结果及相关性的分析表明:力学指标Evd与k30,Ev2与K30由于受填料种类、级配等的影响,其直接线性相关性较差,但Evd与K30,Ev2与K30可以用同一函数拟合,其间接相关性良好;由Ev2与K30拟合函数分析表明,现...

关 键 词:高速铁路路基  粗粒土  压实检测  相关性  压实度

Abstract:Through compaction test of K30,Ev2,Evd and porosity n of the second double line of Lan-Xin railway subgrade test section,the results of four test and its correlation were analyzed.The analysis shows that: because of the various filler type,size distribution,the direct linear correlation of Evd and K30,Ev2 and K30 is poor.But the correlation between Evd and K30,Ev2 and K30 can fitting by a special function,so their indirect correlation is better.It is showed that by the fitting function of Ev2 and K30,standa...
Keywords:high-speed railway subgrade  coarse grained-soil  compaction detection  correlation  degree of compaction K
