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.

Key words: saline soil in inshore, solidified soil with lime, salt content, consistency, compaction test, conductivity
