The mechanical properties of hydraulic concrete are an important influencing factor on the stability of hydraulic engineering facilities. A fine damage intrinsic structure model considering the effect of sulfate corrosion was established using a combination of mechanical experiments and theoretical analysis. The results show that the effect of sulfate corrosion increases the damage degree of concrete after damage. With the increase of corrosion time, the compressive strength and elastic modulus show an exponential decay law, and the damage strain tends to increase. From the experimental results, the shape parameter m and scale parameter ε0 are calculated. Besides, the mesoscopic damage constitutive model considering the effect of sulfate corrosion is solved. The reasonableness of the theoretical model for predicting the stress-strain relationship was verified by experimental data. The constitutive model proposed in this study can provide scientific reference for the accurate prediction of mechanical behavior of hydraulic concrete.
