Abstract :
Abstract Due to the reduction of water resources and frequent droughts and the proper storage and proper use of water resources, the design and implementation of large concrete dams has increased dramatically. Construction is one of the most engineering structures in man-made agriculture, which also in the design stages and in the process of implementation, special attention is required. Most large and high dams are constructed concrete (weighted, arched and arched). The concrete structures of concrete dams and their dimensions over time Due to various atmospheric and environmental degradation factors, such as hydrostatic and hydrodynamic loads, temperature variations and freezing, they are eroded and disrupted. Due to the great cost of constructing dams, concrete dams construct maintenance and rehabilitation methods are of great importance. Nowadays, using sensors and fiber optics, using precision instruments and Exploration wells can be used to find damaged parts of the dam that have undergone necessary repair and rehabilitation measures. In this article, the methods of restoration and reinforcement of concrete dams in different conditions are discussed and solutions to Design and implementation of more durable structures is proposed.
