Abstract:  The dispersed soil has very poor water stability and is prone to damage such as pipe surges, caves, gullies and other damage. The seasonal frozen soil may enhance its dispersion during the freeze-thaw cycle in seasonal freezing area. In order to study the effect of different calcium agents on soil dispersion improvement and the influence of freeze-thaw cycle on the improvement effect, first，two kinds of calcium ionizers, calcium oxide and calcium chloride, were used to improve the dispersed soil in the western area of Jilin, and the optimum mixing dosage was determined to carry out the freeze-thaw cycle test. Then, the influence of freeze-thaw cycle on the improvement of soil dispersion was discussed by dispersive identification test, unconfined compressive strength test and microstructure test respectively. The test results showed that the improvement effect of calcium chloride on soil dispersion in western Jilin was better than that of calcium oxide, and the optimum mixing dosage of calcium oxide for improving dispersed soil was 1.6%, while the optimum mixing dosage of calcium chloride for improving dispersed soil only was 0.4%. The calcium chloride improved soil of 0.4% was used in freeze-thaw cycle test, it was still non-dispersive soil after different times of freeze-thaw cycle, and its unconfined compressive strength was a significant decline in the number of freeze-thaw cycles of 0-5 times. However, the decline tendency slowed down and the compressive strength was basically at 60 kPa after more than ten freeze-thaw cycles. By observing the scanning electron microscope images of the improved soil with 0.4% calcium chloride in different times of freeze-thaw cycles, it is assumed that the state of the cracks and pores of the improved soil tend to be stable after 10 times of freeze-thaw cycles. The above test results show that calcium chloride can be used as a good ameliorator to improve the soil dispersion in seasonal freezing zone.

Key words: dispersed soil, calcium chloride, calcium oxide, freeze-thaw cycle, unconfined compressive strength, microstructure
