摘要
本文旨在通过有限元分析,预测船闸混凝土结构在施工过程中的温度分布,以避免裂缝的产生.利用MIDAS软件,结合环境气象资料、施工方案设计和混凝土试验确定的热力学参数,模拟了船闸混凝土与冷却管及环境的热交换.分析了二闸室段混凝土结构的温度场,并提出了温控和结构措施建议,以控制温度应力和裂缝的形成.研究结果表明,通过合理控制施工工序和混凝土浇筑厚度,可以有效降低温度应力,防止裂缝的产生.
Abstract
This paper aims to predict the temperature distribution of the concrete structure of a ship lock during the construction process through finite element analysis to prevent the occurrence of cracks.By using MIDAS software,combined with environmental meteorological data,construction plan design,and thermodynamic parameters determined by concrete tests,the heat exchange between the concrete of the ship lock,cooling pipes,and the environment was simulated.The temperature field of the concrete structure of the second lock chamber section was analyzed,and suggestions for temperature control and structural measures were proposed to control temperature stress and the formation of cracks.The results indicate that effectively controlling construction procedures and concrete pouring thickness can significantly reduce thermal stress and prevent cracks.
