水泥土无侧限抗压强度影响因素的灰色关联度分析
Influence factors of unconfined compressive strength of cement-treated soil based on grey relevant degree theory

通过水泥土无侧限抗压强度室内配比试验,总结无侧限抗压强度的主要影响因素。运用灰色系统理论的关联度分析方法,分析水泥掺入比、土样含水率和有机质含量对水泥土无侧限抗压强度的影响。研究结果表明:水泥掺入比对水泥土无侧限抗压强度影响最大,其次是土样有机质含量,含水率对水泥土无侧限抗压强度影响最小。本文的研究结果可为今后类似工程提供借鉴。
Based on the data obtained from the experiment of unconfined compressive strength (UCS)of cement stabilized soil. the factors that contribute to UCS were investigated,and three parameters,namely cement ratio, moisture content,and organic content,were regarded as the main factors. Then grey correlation theory was applied to analyse the correlation between these parameters and UCS of cement stabilized soil. It is shown that the influence of cement ratio and organic content is larger than moisture content. This study provides reference for the design of other similar projects
