摘要
通过化学分析、SEM电镜扫描分析、无侧限抗压强度等实验 ,研究了ISS加固粉土质砂和砂质低液限粉土的微观结构及其强度特征 .结果表明 :ISS的掺入 ,使土体易于压实 ,孔隙体积减小 ,密实度提高 ,从而提高土的强度 .ISS加固土中适量掺入水泥 ,可以明显提高加固土的早期强度 ,且能生长出纤维状矿物 ,充填在土颗粒之间的孔隙中 。
Based on the chemical analysis test, SEM electron microscope scanning test and unconfined compressive strength test, this paper researches the microstructure and strength characteristic of the ISS stabilized silty sand and the low liquid sandy silt soil. The research result shows that the addition of the ISS makes it easier to compact and raises its density and strength. When certain dose of cement is added to the ISS stabilized soil, some fiber grows fixing the pore of soil grain. Early strength of the stabilized soil is improved obviously. The strength and the capability of deformation resistance of the mixture increase obviously.
