大体积混凝土温度控制技术在双嵌水库中的应用

Application of Temperature Control Technology of Mass Concrete in Shuanghou Reservoir

摘要:

水库工程施工中广泛采用大体积混凝土来构建挡水和泄水结构,以保证其长期稳定与安全。由于大体积混凝土在施工过程中会产生大量的水化热,使得混凝土内部与外部的温差增大,容易产生温度裂缝,从而影响整体结构。因此,温控技术应用成为水库工程中必要的施工手段。本文通过分析大体积混凝土温控的必要性,探讨水库工程中常用的温控方法及其应用效果,确保水库混凝土结构的质量和使用寿命。

Abstract:

Mass concrete is widely used in reservoir projects to construct water-retaining and water-discharging structures to ensure their long-term stability and safety. Since a large amount of hydration heat is generated during the construction of mass concrete, the temperature difference between the inside and the outside of the concrete increases, and temperature cracks are likely to occur, thus affecting the overall structure. Therefore, the application of temperature control technology has become a necessary construction method in reservoir projects. By analyzing the necessity of temperature control of mass concrete, this paper explores the commonly used temperature control methods and their application effects in reservoir projects to ensure the quality and service life of the concrete structures of the reservoir.
