摘　　要：针对高寒地区建设的碾压混凝土坝因气候条件恶劣常出现混凝土裂缝问题,采用三维有限单元法对某高寒区混凝土坝体运行期温度场进行了表面保护材料的敏感性仿真分析,探讨了恶劣气候环境条件下碾压混凝土坝的温度场及应力场分布规律,给出了适合该工程的优化温控措施,可供相似工程实施温控措施借鉴。As to RCC dam in severe cold area, reasonable measure of temperature control is the crucial issue to prevent concrete from yielding cracks. According to an engineering project, sensitivity simulation study was performed on temperature field of RCC dam about surface protection material. It discussed temperature field distribution regularity of RCC dam in poor climate environment and showed optimized temperature controlled measure which is fit to the project.
