Experimental Study on Mechanical Properties of Self-compacting Cemented Soil Under Wet-Dry Cycles
In order to explore the effect of dry-wet cycles on the mechanical properties of self-compac-ting soil-cement,the unconfined compressive strength of self-compacting cemented soil under different dry-wet cycles was compared and analyzed through experiments,and the appearance damage degree and strength deterioration law of self-compacting cemented soil were discussed.According to the strength de-cay law,an empirical formula between the dry-wet cycle number and strength deterioration was estab-lished.It is found that the strength decay rate of self-compacting cemented soil after the jth dry-wet cy-cles is j 0.3 times that of the first cycle.The peak strength of the stress-strain curve of self-compacting cemented soil gradually decreases with the increase of the number of dry-wet cycles,and the failure type of sample changes from brittle failure to plastic failure.
