摘　　要：温度的变化及其产生的影响在大体积混凝土结构中是不容忽视的。分析温度场、研究温度裂缝以及进行温控设计、制定合理的温控防裂措施是工程中非常关注的问题。为此,以某大体积混凝土水闸墙现场监测温度为基础,分析大体积混凝土温度场的计算原理,主要阐述用ANSYS程序实现对大体积混凝土水闸墙温度场的数值模拟,结合工程实际,进行了温度场的分析,分析表明,数值模拟结果与现场监测结果较为吻合。通过温度场的分析,可准确地预测大体积混凝土浇筑后温度场的变化,及时制订、采取温控措施。The influence produced by the temperature change cannot be ignored in massive concrete structures.In engineering,much attention is paid to analysis of the temperature change,study on thermal cracks,designs of controlling the temperature change and drawing up reasonable measures of controlling the temperature change.According to the monitored temperature data of a massive concrete sluice wall,the theory of calculating temperature field of massive concrete is analyzed,and expatiation is made on how to simulate the temperature field change of the massive concrete sluice wall through ANSYS.Based on simulating the temperature field of the project,the study shows that simulated result is more consistent with the monitored result.Through the simulation analysis of temperature field,the temperature field change of massive concrete poured can be predicted accurately,and temperature control measures can be developed and taken timely.
