Abstract

Abstract

Freeze-thaw cycles are one of the important factors causing mechanical damage of soil. To study the strength characteristics of fluidized solidifiable soil integrated by collapsible loess and red sandstone experienced freeze-thaw cycles, mechanical and scanning electron microscope tests were conducted on the fluidized solidifiable soil experienced different rounds of freeze-thaw cycles by indoor tests, and the variable regularities of physical and mechanical parameters and energy dissipation mechanisms of the fluidized solidifiable soil with different mix proportions experienced freeze-thaw cycles were analyzed. The results indicated that the red sandstone content, water content and cement content increased with the rounds of freeze-thaw cycles and had different effects on compressive strength. To mix red sandstone could effectively improve the compressive strength of fluidized solidifiable soil. The relation between compressive strength and the rounds of freeze-thaw cycles complied with a decreasing exponential function relation. The main mechanical indexes, including elastic moduli, masses, cohesion, internal friction angles and strain energy densities, decreased with the increase in the red sandstone content and the rounds of freeze-thaw cycles. Combining with the results by SEM, the variable regularity of microstructure of fluidized solidifiable soil damage by freeze-thaw cycles was analyzed. That freeze-thaw cycles could change the microstructure constructed by red sandstone particles was pointed out, and thus the mechanism of energy dissipation of fluidized solidifiable soil experienced freeze-thaw cycles was clarified.
