Abstract: In order to explore the effect of freeze-thaw action on the shear strength of vegetation-growing concrete, we took cold-end temperature, water content and thawing temperature as influencing factors to monitor cohesives and internal friction angles of initial and frost-thaw samples by quick shear test. The results showed that after a process of frost-heave and thaw-settlement, vegetation-growing concrete cohesive reduced, but its internal friction angle increased in most cases. The coupling effect of cohesive and internal friction angle indicated that vegetation-growing concrete shear strength decreased. As the cold-end temperature dropped, vegetation-growing concrete cohesive decreased and its internal friction angle increased gradually after the process of frost-thaw. The moisture content had a dual effect on the cohesive and internal friction angle of vegetation-growing concrete. With the increase of moisture content, the cohesive decreased rapidly at first and then decreased slowly to a stable value finally, but the internal friction angle kept declining all the time. The change of thawing temperature had no effects on the changes of cohesive and internal friction angle except on the thaw-settlement time of vegetation-growing concrete.
