石灰改善土在合六高速公路路基工程中的应用

The application of lime improvement soil in the roadbed project of He-liu expressway

介绍了在安徽膨胀土地区路基施工中,由于膨胀土存在压实困难、裂隙发育、易风化、吸水膨胀降低强度等缺陷,为解决填料短缺,降低工程造价,提高路基强度和整体稳定性,采用在膨胀土中掺石灰,改善膨胀土的结构,达到提高路基填筑质量的目的。

Introduced the roadbed construction in the inflation soil area of Anhui province, because the inflation soil existence compaction difficulty, the crevasse growth, easy to make decent, the absorbing water inflation reduces flaws and so on intensity, for solving the padding to be short, reducing the project construction cost, enhancing the roadbed intensity and the overall stability, used to mix the lime inthe inflation soil, to improve inflation soil structure, achieved the goal of improving the roadbed reclamation quality.
