摘　　要：采用有限元方法,模拟外界气温、地质及施工过程等,对闸首底板混凝土施工期的温度场及温度应力场进行实时仿真计算,分析泥岩基础上混凝土底板的温度应力特征,指出要注意混凝土结构膨胀阶段和收缩阶段温度应力的控制,并提出控制措施,为类似工程的设计与施工提供依据和参考。The paper simulates the temperature field and thermal stress field in lock-head floor built on mudstone foundation, and analyzes the feature of thermal stress by FEM. Furthermore, it is pointed out that attention shall be paid to control of thermal stress during concrete expanding period and shrinking period. The results may serve as a reference for design and construction of similar projects.
