摘要
采用强夯处治宜章—凤头岭高速公路大面积高液限红粘土填方路基,并开展了现场试验研究。试验结果表明:强夯法处治高液限红粘土填方路基效果良好,夯后填土的物理力学性质及抗剪强度有明显改善和提高,可提高路基工程质量。
Large area of high liquid limit red clay filled subgrade of Yizhang-Fengtouling Expressway is treated by dynamic compaction and field study is carried out.The result shows that dynamic compaction achieved good effect for treatment of high liquid limit red clay filled subgrade.The physical mechanical properties and shear strength of compacted filling soil are significantly improved and increased,which can inprove the quality of subgrade engineering.
