摘要

用石灰固化不同含盐量的滨海盐渍土，固化后土微结构参数发生了变化，力学强度大幅度提高。多元逐步回归分析计算结果表明二者之间存在着良好的相关关系，颗粒粒度分维、颗粒定向分维、等效直径、扁圆度和面积比是对固化土力学强度影响较为显著的5个微结构参数。借助土微结构参数与强度间的相关性计算分析，从另外一个角度验证石灰对滨海盐渍土的固土作用。

Abstract

Solidifying saline soil in inshore with different quantities of salt using lime

which causes the microstructure indices and strength of saline soil change obviously and increase greatly. It has been proved that strength has good correlation with microstructure indices with the help of multivariate stepwise regression method; and the five indices

including particle granularity fractal

particle orientation fractal

particle diameter

particle oblate degree

and particle area ratio

are the significant indices effected on the strength of solidified saline soil in inshore with lime. According to calculation results of microstructure indices

its fractal

and strength

solidifying mechanism of lime-saline soil can be certified from another aspect.
