摘要
通过对生、熟石灰的改良土在不同掺灰量下进行无侧限抗压强度试验,探求不同掺灰量改良后土的强度关系,并通过其改良机理及反应方程,获取生、熟石灰改良效果差别的定量关系。结果表明:相同的掺灰量下,生石灰改良土的最大干密度、最佳含水量和无侧限抗压强度较熟石灰的改良土都要大;但生、熟石灰改良土最佳掺灰量所能达到的最大无侧限抗压强度相差无几。
Undefined compression strength tests were designed to study the relationship between the soil strength and addition ratio of quicklime or slaked lime. The effect differences between the quicklime and slaked lime were determined through modification mechanism and reaction equation. The result shows that the maximum dry density, optimum water content and unconfined compression strength of the quicklime is higher than that of slaked lime in the same ratio,while the maximum unconfined compression strength of the two improved soils is roughly the same.
