| 摘 要： | 滞洪区亚砂土、亚粘土用作路基基层、底基层填料土必须进行固化改良,该文采用石灰-粉煤灰、水泥-粉煤灰组合和水泥-石灰组合对其进行改良研究,将以上改良土按照不同配合比,以不同的含水率进行击实试验,确定最优含水率及最大干密度,并分析两者随不同掺灰比的变化规律,供工程参考。 |
| 关 键 词： | 路基填料 改良土 击实试验 最优含水率 最大干密度 |

| Abstract: | Sand loam and mild clay of low subgrade must be improved when used as subgrade subbase course in flood storage and detention areas. Different mix proportions of lime-fly ash,cement-fly ash and cement-lime are proposed for improving the soils. In order to determine the optimum water content and maximum dry density,tests are done under the different water contents. The reseach results could offer reference to projects. |
| Keywords: | embankment filling materias improved soil compact test optimum water content maximum dry density |
