In the early stage, the complex geometry of arch dam restricted the development of arch dam. With the development of time and the expansion of project scale, the improvement of design theory, calculation and construction technology of arch dam has been greatly promoted. Especially the advent of computer accelerated the development of arch dam. It simplifies a lot of calculation, shortens the calculation cycle and improves the calculation accuracy. Optimization technology, CAD technology and artificial intelligence system have been gradually applied and developed in arch dam design. In terms of construction, with the development of concrete technology and the research and development of engineering equipment, the engineering technology of arch dam has been developed and improved to varying degrees. The safety and efficiency of arch dam have been improved. In the future water conservancy construction, arch dam is increasingly important.
