所谓大体积混凝土,是指其结构尺寸已经大到必须采取相应技术措施妥善处理温度差值,合理解决温度应力并控制裂缝开展的混凝土。由于大体积混凝土工程的条件比较复杂,施工情况各异,再加上混凝土原材料的材性差异较大,因此控制温度变形裂缝就不是单纯的结构理论问题,而是涉及结构计算、构造设计、材料组成和其物理力学性能以及施工工艺等多学科的综合性问题。
The so-called mass concrete, refers to the size of the structure has been large enough to take appropriate technical measures to properly handle the temperature difference, reasonable solution to temperature stress and control the development of cracks in the concrete. Due to the complex conditions of mass concrete construction and the different construction conditions, as well as the great differences in the material properties of concrete raw materials, controlling temperature deformation cracks is not a simple structural theory issue, but involves structural calculation, structural design, material Composition and its physical and mechanical properties and construction techniques and other multidisciplinary comprehensive issues.
