摘　　要：在水利工程中,混凝土以其优点,成为运用最为广泛的水工建筑材料之一。但是混凝土由于其自身特点,在浇筑及凝结过程中不可避免地会产生裂纹、空洞等缺陷,随着时间的推移,在外界物理、化学等作用下不可避免的产生损伤破坏。以往对混凝土破坏的研究常常从宏观结构出发,不能反应混凝土破坏的实质。从水工混凝土损伤角度,总结了损伤的表现形式、损伤的机理以及研究方法,为今后水工混凝土损伤研究提供了依据。In water conservancy engineering, with its advantages, concrete become one of the most widely used hydraulic construction ma- terials.But due to its own characteristics,in the process of casting and condensation concrete will inevitably produce the flaws such as crack, hollow.With the passage of time,in the physical, chemical and other effect,inevitablly damage is caused.Previous study of concrete damage is in macrostructure, often can＇ t reflect the essence of the concrete damage.From the angle of hydraulic concrete damage, summarizes the mani- festation of damage,injury mechanism and research methods,provided the basis for the hydraulic concrete damage research in the future.
