The three states of saline soil are different from the common soil

the salt liquor and salt in soil granule have a homeostasis with the changing of the outside environment (such as temperature

humidity and artificialness)

there may be easy to have engineering disasters when the saline soil is used in roadbed

such as the frost boil

the expansion of saline soil

the dissolve falling

the roadbed soil pickled and so on. Aiming at analyzing the saline soil characteristics and the improving mechanism

the treated method is brought forward. The results of study indicate that adding the improving stabilizer into saline soil can improve the CBR property greatly and can meliorate the stability of sucking water clearly

make the soil melioration

finally

gain the solution of the problem of the disasters in roadbed.
