含盐量对石灰固化滨海盐渍土微结构参数的影响

因土中含有较多的氯盐，引起了石灰固化滨海盐渍土的微结构变化。采用Leica QWin5000图形处理软件对石灰固化滨海盐渍土的SEM照片进行统计，证实随着含盐量的增加，固化土颗粒的等效直径、扁圆度、面积比和充填比等微结构参数呈近线性变化。含盐量增加使得固化土颗粒的粒度分维值增加，颗粒的均一化程度越来越差；而颗粒定向分维则先升、后降、再逐渐趋于一个稳定值，即固化土颗粒的排列方向保持不变。固化土颗粒级配测试结果也与上述变化规律相吻合。

Effect of salt content on microstructure indices of solidified inshore saline soil with lime

Solidifying inshore saline soil with lime, which causes the microstructure indices of saline soil change obviously because of a lot of chloride. With the help of Leica QWin5000 software it has been proved that microstructure indices, including particle diameter, particle oblate degree, and particle area ratio, increase or decrease at approximately linear relationship with the increase of salt content through analyzing SEM’s photos. With the increase of salt content fractal dimension of particle granularity has been increased; and uniformity degree of particles diameter has been decreased; however fractal dimension of particle orientation rises firstly; secondly decreases, and finally is stable progressively; and orientation of particle is fixed in the some direction. And the conclusion is corresponding with the results of particle size analysis of solidified soil.
