摘要: 以粉砂土为研究对象,对水泥土抗压强度与水泥含量关系进行了试验研究,推导了水泥土结构形成过程中水泥浆包裹土颗粒和填充孔隙所分别对应水泥量的理论计算公式。在此基础上,对水泥含量不同时,水泥在固化土结构形成过程中所起不同作用及其与水泥土抗压强度增长规律相互关系进行了分析,提出固化土结构形成由固化剂胶结土颗粒与填充孔隙两部分构成。

Abstract: For silt,the relationship between the strength of stabilized soils with various cement contents and the cement content was investigated experimentally,and the formula of cement contents for wrapping soil particle and filling pore during the structural formation of the stabilized soil was derived.Then,the relationship between effect of cement content on the structural formation and the increase of the strengths of the stabilized soils with various cement contents was analyzed,and it was shown that the structural formation of stabilized soil consisted of soil particle cementing and pore filling.
