The Test Analysis on Frost Heave Characteristics of Carbonated Saline Soil
In order to study the frost heave characteristics of the carbonated saline soil, we have selected the carbonated saline soil sample of Da-An area in western Jilin province as the research object and analyzed the influence to the frost heave rate caused by the temperature, water content, compaction degree of soil sample, salt content, etc by indoor physical, chemical test and frost heave test. The results show that: the frost heave rate increases with the moisture content; On the bases of the certain salinity and moisture content, the frost heave rate has a increasing trend along with the increased compaction degree, but also there is the best frost heave compaction degree; Temperature changes have a great impact on the soil frost heave rate, gradually reducing the temperature, the frost heave deformation of the saline soil sample increases gradually, when the temperature down to -10 °C, the deformation are stabile; The frost heave rate increases almost with the salt content, which is for that if the salt content is larger, then the soil sample freezing point is lower, so the frozen works will last for a longer time, also the eventually larger frost heave rate.
