摘　　要： 通过对固化土进行强度试验,在最佳固化剂掺量的条件下,以掺加纤维的固化土与未掺加纤维的固化土在不同的养生龄期下进行强度分析。根据图表数据对比,得出结论:固化土的抗压强度随固化剂的掺量增加而增加,并通过分析,确定10%的固化剂掺量为最佳掺量;养生龄期与抗压强度的增强是同步的,但主要前期强度增加较大,后期强度增加较小;纤维固化土的抗压强度,主要是随着固化剂掺量以及龄期的增加而增强,但与未掺加纤维的条件相比,在养生龄期的前期,强度增加较高,但后期强度增加较小;固化土加入纤维后,试件抗拉性能增加了93%,满足基层要求。 Through strength test of the cured soil, the strength analysis was carried out under different curing period under the condition of the optimum curing agent content, and the cured soil with fiber and the fiber without fiber were analyzed. According to the chart data, it is concluded that the compressive strength of the cured soil increases with the increase of the content of the curing agent, and the dosage of 10% curing agent is determined as the best dosage by the analysis. The increase in the age of birth and the compressive strength are synchronized, and mainly prominent in the early state. The compressive strength of the fiber-cured soil mainly increases with the increase of the curing agent and the age of the curing agent, but compared with the non-doped fiber condition, the strength increases more in the early stage of curing age than in the late stage. After adding the fiber to the cured soil, the tensile properties of the specimen is increased by 93%, meeting the basic requirements.
