摘要

随含盐量的增加，滨海盐渍土中的盐分结晶形成了许多晶体颗粒，改变了土的颗粒级配和微结构形式，使土的力学强度发生变化。无侧限抗压试验和三轴压缩试验结果表明，随含盐量的增加，石灰固化土的无侧限抗压强度和抗剪强度降低；随养护龄期的增加，石灰固化土的无侧限抗压强度和抗剪强度增加；随含盐量的增加，固化土试样浸水和不浸水无侧限抗压强度之间的差值越来越小。工程应用滨海盐渍土时需控制土的含盐量。

Abstract

With the increasing of salt content of saline soil in inshore

salt crystals particles are formed in soil

which causing the microstructure and strength of solidified soil change obviously. According to results of unconfined compression test and triaxial shear test

unconfined compression strength and shear strength of the solidified lime-soil decreases with more salt content and increases with more curing period. Meanwhile

the difference of unconfined compression strength of solidified lime-soil in water and in air decreases gradually with more salt content. Therefore salt content of soil shall be limited in the stage of engineering construction.
