摘要
在进行核电站安全壳结构的整体性能试验时,大气环境作用会干扰结构试验变位和应变的测试结果。为了了解环境影响的规律和幅度,从理论和试验验证上探讨了安全壳在大气环境下的温度场问题,建立了时程分析和估值的计算模式,研究了有关参数。编程计算结果与实测结果非常吻合。本研究对大型结构设计和探讨混凝土和砖混结构建筑顶层开裂的热作用规律也具有实际意义。
The Structural integral test of nuclear power station PCCV is one kind of precision test under low load. The strain and displacement in the process of test will be influence by atmosphere circumstance . The effect of the temperature field under atmosphere circumstance to the PCCV test is studied in detail from both the theory and the test. Both the heat transfer difference e-quations and the elevation formula are established. At same time, a computer program is developed to run some examples. The computing results are well agreed with that of the test.
