基于轴向拉伸与压缩试验观测资料，论述了高强度混凝土的细观损伤机理和以应力与应变全曲线及其特征点相对应参数建立的损伤本构模型，提出了拉、压二向应力状态时的本构模型和正交异性损伤本构模型，同时还引入其他学者提出的混凝土三向应力状态各向同性损伤时的本构模型，并提出了高强度混凝土的损伤断裂判据 Based on axial tensile and compression experimental observation data, the meso-damage mechanism of high-strength concrete and the damage constitutive model established by the corresponding parameters of stress and strain curves and their corresponding characteristic points are discussed, and tensile and compressive biaxial stresses are proposed. The constitutive model and the orthotropic damage constitutive model in the state, and the constitutive model proposed by other scholars for the three-dimensional isotropic damage state of the concrete, and the damage fracture criterion of the high-strength concrete is proposed.
