纳米二氧化硅改性石灰土的无侧限力学特性研究

Study on Unconfined Mechanical Properties of Nano-silica Modified Lime Soil

稳定法是用于改良土壤的传统方法,但传统材料在生产过程中会排放出对环境污染严重的气体,这就迫使我们寻找新型材料来代替传统材料。本研究提出了利用纳米二氧化硅(Nano-SiO2简称"NS")来改善石灰土的强度,通过无侧限抗压强度试验对其进行研究。根据试验结果显示,随着NS含量的增加,石灰土的无侧限抗压强度逐渐提高。且当NS含量为0.6%时,其强度的提高幅度最大。

The stabilization method is a traditional method used to improve the soil,but traditional materials emit serious environmental pollution during the production process,which forces us to find new materials to replace traditional materials.This research proposes the use of nano-silica(Nano-SiO2 for short"NS")to improve the strength of lime soil,which is studied through unconfined compressive strength tests.According to the test results,as the content of NS increases,the unconfined compressive strength of lime soil gradually increases.And when the NS content is 0.6%,its strength increases the most.
