Abstract

As the scale of large water conservancy projects continues to expand, mass concrete construction has become a critical technical component. The increase in concrete volume leads to the concentrated release of hydration heat, which easily causes temperature stress and cracking problems, thereby affecting structural stability and project quality. In view of the construction characteristics of large-scale water conservancy projects, this paper systematically analyzes mass concrete construction technology, with a focus on key technical approaches such as raw material control, temperature control measures, and optimization of construction processes. Through the rational control of pouring procedures, strengthened temperature management, and an improved quality monitoring system, the probability of temperature cracking can be effectively reduced and the overall stability of concrete structures can be enhanced. Engineering practice shows that the scientific application of mass concrete construction technology can significantly improve the construction quality of large-scale water conservancy projects and provide technical reference for related engineering practice.
