桥梁结构中大体积混凝土的水化热分析研究

Study of Hydration Heat of Massive Concrete in Bridge Structure

温度应力的分析和控制是防止裂缝的主要措施,是大体积混凝土设计和施工的前提。结合实例,利用大型结构计算有限元程序MIDAS/Civil对水化热分析的原理和方法进行了说明,并得出了一些结论。

Analysis and control of temp stress are major measures to avert crack, the premise of design and construction of massive concrete. The paper explains the principles and methods for hydration heat analysis by finite element program MIDAS/Civil for calculation of large scale structure, and draws some conclusions.
