Recently, the utilization of nanomaterials has been gaining popularity in soil improvement procedures. The aim of this study is to investigate the feasibility of using nano-MgO (NM) along with fibers (FBRs) to improve clay soil's load-bearing capacity and settlement by using both conventional and model experiments. First, the optimum water content values for NM-clay mixtures were determined by compaction tests. For mixtures prepared with the optimum water content, the addition of 1.5% NM alone resulted in a 1.33-times improvement in bearing capacity, and the addition of 1.5% 90 mm FBRs alone led to a 1.83-times improvement. Utilizing 1.0% NM and 1.5% FBRs at 90 mm long resulted in a 3.07-times improvement in bearing capacity. The temperature of the mixing water was found not to be a significant parameter, and curing duration impacted the results only for NM addition. Significant settlement improvements were achieved by adding the two materials together. Therefore, utilizing NM and FBRs together resulted in an optimal outcome for clay soil.
最近，纳米材料在土壤改良过程中的应用越来越普遍。本研究的目的是通过传统实验和模型实验，研究使用纳米氧化镁（NM）和纤维（FBRs）来提高粘土承载能力和沉降性能的可行性。首先，通过压实试验确定了NM-粘土混合物的最佳含水量值。对于以最佳含水量制备的混合物，单独添加1.5%的NM可使承载能力提高1.33倍，单独添加1.5%的90毫米FBRs可使承载能力提高1.83倍。使用1.0%的NM和1.5%的90毫米长的FBRs可使承载能力提高3.07倍。发现拌合水的温度不是一个重要参数，养护时间仅对添加NM的结果有影响。将两种材料一起添加可显著改善沉降。因此，将NM和FBRs一起使用可使粘土获得最佳效果。
