混凝土在现代工程建设中占有重要地位。在大体积混凝土中,温度变化对结构的应力状态具有显著的不容忽视的影响,因此,掌握温度应力的变化规律,对于进行合理的结构设计和施工极为重要。
Concrete occupies an important position in the construction of modern engineering. In mass concrete, the temperature change has a significant impact on the stress state of the structure. Therefore, mastering the variation law of the temperature stress is very important for proper structural design and construction.
