摘要

随着含盐量的增加，滨海盐渍土中的盐分结晶形成了更多的盐颗粒，使石灰固化土的稠度指标发生变化，总体上分阶段逐渐下降。含盐量的增加使得石灰固化土的不均匀系数增大，且随着养护龄期的增加而增大。增加土的含盐量，则石灰固化土悬液的电导率随之增加，但电导率几乎不随养护龄期而变化，这表明氯盐没有参与石灰的固化反应，只是吸附在土颗粒的表面或存在土孔隙中，石灰固化后的盐渍土仍然具有一定的吸湿软化性。重型击实试验结果证实，增加含盐量使石灰土混合料的最大干密度略有降低，最优含水率则几乎不变，因此，施工中可不考虑含盐量对石灰固化滨海盐渍土现场碾压效果的影响。

Abstract

With the increase of salt content of saline soil in inshore

the salt particles are formed in soil

in general

which presenting an appearance of different sections and causing the consistency indices of solidified soil drop gradually. Uniformity coefficient of the solidified soil with lime increases with more salt content and more curing periods. Conductivity of the solidified soil has been increasing with more salt content and increasing hardly with more curing periods. It has been certified that salt has no action in the chemical reaction of lime and soil

salt is still on the surface of soil particles or in the pores of soil

and the solidified soil will be softened because of absorption of water. It has been proved that maximum dry density drops slightly; and optimum water content is hardly change with the increase of salt content on the basis of compaction test; and in situ salt content effects scarcely on compactness of saline soil in inshore with lime.
