抄録

Heaving tests were conducted to study the characteristics of frost heaving in soils under tri-axial stress in an open system apparatus, in which the stress σ₁ in the direction of heat flow and stress σ₃ in the rectangular direction of heat flow were arbitrarily assigned to the specimen. Frost expansion occurred not only in the direction of heat flow but also in the rectangular direction and depended on σ₁ and σ₃. A σ₁ increased, the frost heave ratio ξ₁ in the direction of heat flow decreased and frost heave ratio ξ₃ in the rectangular direction increased. A σ₃ increased, ξ₁ increased and ξ₃ decreased. Volume frost heave ratio ξ_v decreased with the increase in σ₁ or σ₃, but the decrease tended to stop when these stresses increased above a certain value. The experimental results of ξ₁ and ξ₃ could be fitted to the experimental formulas expressed as a function of σ₁ and σ₃.The results from a different heaving test, performed by confining the specimen in a cylinder, were in satisfactory agreement with the values calculated by formulas based on ξ₃=0.
