摘　　要：混凝土大坝浇筑过程中普遍存在裂缝现象,对于大坝温度应力的正确把握,合理的温控措施对指导混凝土施工意义重大。文章结合工程实例,选用不同的温控防裂措施,利用ANSYS软件有限元分析坝体施工期温度场和徐变应力场,通过计算成果得出不同月份最合适的温控措施,对于指导实际施工具有一定的参考意义。There exists crack appearance commonly during the course of concrete dam pouring,to size the dam temperature stress correctly and control the temperature reasonably will be of significant for guiding the concrete construction. Combined with the project case,to select different temperature control measures,this study used ANSYS software finite element to analyze the temperature field of dam body in the construction period and the creep stress field,through the calculation results,to obtain the temperature control measures suitable most in each month,having a certain of reference meaning for guiding practical construction.
