摘要
通过室内水泥搅拌土不同龄期、不同养护条件、不同灰土比条件下弹性波速和抗压强度的对比实验,探讨了波速、龄期和强度、灰土比之间的相关关系.通过对实验数据的统计分析,发现它们之间存在着非线性关系.分析了用纵波波速和横波波速反推强度及灰土比的可靠性大小,并提出了水泥土波速和强度及灰土比的关系式.研究发现,水泥土横波波速与抗压强度和灰土比有更好的相关关系,用横波波速来反演抗压强度和灰土比有更高的可靠性.
By the contrasting test between the wave velocity and strength of soil-cement in the laboratory at the different time ,the relation between them is argued.After analyzing the data,the nonlinear relation between them is found out.The reliability of strength according to the wave velocity is analyzed,a formula about wave velocity and strength of soil-cement is given.The basis for the harmless survey in soil-cement is provided.
