摘要
在混凝土温度场及温度应力场和施工过程仿真的基础上,考虑大坝混凝土温度应力分布、温度控制难度、施工组织特点及工程质量保证等方面,综合对比大坝混凝土浇筑的不同纵缝分缝方案,提出了适合向家坝水电站大坝工程特点的纵缝分缝方案。
Based on the computer simulation on concrete temperature field,thermal stress field and dam construction process,involving the stress distribution of concrete temperature,the difficulty of temperature control,the characteristics of construction organization and assurance of project quality,the schemes of longitudinal joints on dam concrete construction have been comprehensively compared.The scheme fit for the dam characteristics was given.The scheme ensures high performance in dam construction.
