| 摘 要： | 大体积混凝土在施工中容易产生温度裂缝,降低了混凝土的完整性,影响坝体的安全,因此对温度场和应力场的研究有重要意义。应用有限元软件的温度场和应力场仿真功能,采用二维有限元程序对碾压混凝土坝的温度场和应力场进行仿真计算,并对其结果进行分析,最终得出温度场与应力场随时间的变化规律。

| Abstract: | The mass concrete in construction is easy to bring about temperature cracks,which may reduce the integrity of the concrete and affect the dam safety.So the study on temperature field and stress field is of great significance.Here,by using the emulation function of finite element analysis software and adopting 2D finite element program,the temperature field and stress field of some RCCD are calculated,and the calculation results are analyzed.At last,the variation rules of the temperature and stress field with time are concluded. |
