| 京沪高速铁路三标段路基风化花岗岩填料改良试验研究(49 卷) |
| 英文标题 |
| Experimental study on improving subgrades filling material of weathered granite at 3ed contract section for Beijing-Shanghai high speed railway |
| 摘要 |
| 京沪高速铁路三标段路基使用风化花岗岩填料进行填筑，对不同厚度填料和不同碾压遍数压实结果进行分析，指出取土场填筑材料不能满足高速铁路路基填筑质量要求，需用改良土，对三种掺和料的改良土进行压实试验，结果表明掺石灰土和碎石土能对原土填筑压实参数起到显著改善作用 |
