摘　　要：混凝土结构工程的老化或功能缺陷是病险水库最为常见的病害之一。论述了混凝土坝常见的缺陷及相应修补加固材料必须具备的性能。介绍了新近研制的一些修补加固材料及其在工程中的应用情况,包括高强环氧灌浆材料、新老混凝土界面粘结材料、钢筋锚固材料、混凝土抗冲磨修补材料、防渗堵漏材料、碳化修补材料。这些材料均具有优异的性能,能满足混凝土坝工程修补加固的要求,具有显著的经济效益,可在类似工程中推广。The aging and function defects are common dangers of the concrete structure projects.We illustrate the common defects of concrete dams and requisite properties of corresponding repair material.Aiming at these requisite properties,we present some newly developed repair and reinforcement material and their applications in engineering practice,including high-strength epoxy grouting material,interface bonding material between old and new concrete,material for steel bar anchorage,abrasion resistant material for concrete repair,permeability resistant material and carbonization resistant material.These materials possess excellent properties and can meet the requirements of engineering reinforcement,while significant economic benefits can achieved as well,which is worth recommending.
