In order to study the damage analysis of sprayed concrete under freeze-thaw cycles and uniax-ial compression,a damage constitutive model of sprayed concrete under freeze-thaw cycles and uni-axial compression was established based on the theory of concrete damage mechanics and thermo-dynamics,as well as the two-parameter WEIBULL distribution probability function and Lemaitre strain equivalence principle.The results of freeze-thaw cycles and uniaxial compression tests on 36 sprayed concrete specimens were analyzed,Discuss the influence of various parameters on the stress-strain behavior of materials,and verify the rationality and applicability of the model.
