| 摘 要： | 单台1 000 MW级机组火电厂主厂房长度超过规范限定值,温度应力是其要解决的主要问题之一.通过手算法分析混凝土的收缩、温度应力和变形,对主厂房超长钢筋混凝土结构温度效应进行了探讨,并用有限元程序进行温度应力的数值计算,得出了结构在温度应力作用下的内力分布及变形特点,对工程设计及施工具有一定的指导意义.

| Abstract: | A reinforced concrete structure for main power house of a thermal power plant with 1 000 MW unit mainly means its length is longer than the maximum value of the structure in the code;and temperature stress is one of the key problems needing to be solved.The analytical methods of temperature stress,temperature deformation and shrinkage of the concrete are discussed;the numerical analysis of overlength concrete structure is carried out by FEM program;and it can be directed to project design and construction. |

| Keywords: | thermal power plant main power house overlength concrete structure temperature stress shrinkage |
