| 摘 要： | 为了研究偏高岭土的掺入对水泥土强度及渗透系数的影响,采用室内试验研究方法,通过用偏高岭土等量替换水泥制作水泥土试块,对不同偏高岭土掺量的水泥土试块在不同养护龄期下进行无侧限抗压强度试验及渗透试验,探究偏高岭土掺量和龄期对水泥土强度和渗透系数的影响。研究结果表明:一定量偏高岭土的掺入能极大地提高水泥土的强度并且减小水泥土的渗透系数,且在偏高岭土掺量为3%时达到最佳,同时表明了水泥土的渗透系数和强度具有较好的线性相关性。

| Abstract: | In order to study the effect of metakaolin on cement soil strength and permeability coefficient, different amounts of metakaolin were added to cement soil. By the method of indoor test,The unconfined compressive strength and permeability coefficient of the cement soil was tested under the condition of different age and metakaolin ratio.And then study the effect of metakaolin ratio and age on the strength and permeability coefficient of cement soil.The test showed that a certain amount of metakaolin can effectively improve the strength of cement soil and reduce the permeability coefficient. And metakaolin admixture of 3% to achieve the best effect. Meanwhile it shows that strength and permeability coefficient have better linear correlation. |

| Keywords: | cement soil metakaolin unconfined compressive strength permeability coefficient age |
