Research on Elastocoast Revetments Frost Heave Adaptability Model Test

Abstract:

Elastocoast revetments frost heave adaptability model test was carried out. Conclusions: (1) Elastocoast revetments can increase heat resistance and decrease the energy transfer. So the frozen depth and amount of frost heaving could be reduced. (2) This structure has deformation characteristics with temperature, and has a deformation at the test beginning. (3) The freezing rate under revetments is slow and the water supply is sufficient, because of which the amount of frost heaving will occur at one third of side slopes of canal, and the bottom of canal take the second place. (4) Consolidation settlement occurred after freeze-thaw cycling. And the revetments have a trend of becoming gentle slope. It indicates that Elastocoast revetments can commendably adapt to frost heave deformation. (5) The freeze-thaw durability is influenced by water content and the dosage of Elastocoast. The capability to resisting freeze-thaw denudation is better with the water content reduce and the material dosage increase.
