摘　　要：有限元法是分析温度应力的有效方法,采用有限元法分析苗尾挑流鼻坎的温度应力,并在此基础上提出相应的温控措施。研究结果表明,该结构夏季浇筑时,需控制浇筑温度19℃,且需要通水冷却措施和养护措施。FEM is an effective method to analyze the temperature stress of mass concrete. FEM is used to analyze the temperature stress of the flip bucket of MIAOWEI power station. On this basis, the corresponding temperature control measures are put forward. According to the calculation results, the placement temperature should be less than 19℃, and pipe cooling method and water cure method should also be used to prevent the concrete from cracking in summer.
