| 摘 要： | 通过颗粒分析、击实试验、中德对比分析试验及土工大三轴剪切试验等,研究武广客运专线路基A,B组填料路基填筑质量控制指标及其强度特性,并考虑填料中细粒土含量的影响。研究结果表明:路基以压实系数作为密实度控制指标是最合理的;衡阳段路基密实度控制指标:基床底层压实系数应取0.95,路基本体压实系数应取0.93;路基施工中碾压荷载应控制在一定范围内,细粒土的含量为6%其路基填筑质量更好。研究成果在该段路基施工中应用,取得了比较理想的效果。

| Abstract: | Through particle analysis,compaction test,China-Germany comparison test and geotechnical triaxial shear test,the quality control indicators and strength characteristics of subgrade filled with A,B filling material of Wuhan-Guangzhou Passenger Dedicated Line are studied considering the influence of fine grained soil content in filling material.It is indicated from the result that subgrade compaction coefficient is the most reasonable indicator for compactness control.Compaction coefficient of bedding bottom ... |
