混凝土作为结构材料而被广泛地应用于工程中,要特别注意它的力学行为即变形和断裂全部过程和特征的研究,探求混凝土的组成、结构与其弹性、塑性、粘性和强度四个主要力学性能之间的关系。从本世纪二十年代开始而发展起来的宏观断裂力学正是以构件中存在原生裂缝或类裂缝为前题,研究裂缝的生长、扩展、断裂的过程和规律,研究抑制裂缝扩展,防止断裂的措施,为工程设
As a structural material, concrete is widely used in engineering. Special attention must be paid to its mechanical behavior, that is, the whole process and characteristics of deformation and fracture, and to explore the four major mechanical properties of the composition, structure, elasticity, plasticity, viscosity, and strength of concrete. The relationship between. The macro-fracturing mechanics developed from the beginning of the 1920s is the premise of the existence of primary cracks or cracks in the components, and studies the process and laws of the growth, expansion, and fracture of the fractures, and studies the inhibition of crack propagation and prevention of fractures. Measures for engineering
