水化热引起的温度裂缝大多发生在结构施工初期、宽度较大且贯通裂缝比较多，对结构的耐久性、透水性会产生严重影响，因此在浇筑时要考虑水化热的影响。论文以某箱梁的根部截面为研究对象，在箱梁中埋设温度传感器，进行现场监测，并用有限元软件建立水化热模型进行水化热分析，将理论数据和实测数据对比分析，研究混凝土水化热温度的变化规律。

Most of the thermal cracks occur at the initial stage of structure construction due to hydration heat. Most of them pass through the structure with wider width. These cracks seri-ously damage the durability and permeability of the structure. As a result, the influence of hydration heat must be considered during the casting process. This paper, base on the research ta-rget of bot om section of a span of box girder, through embe-dding temperature sensors into the girder, them carrying out on site monitoring, with the help of infinite element software to establish a hydration model to carry out hydration analysis, it studied how the hydration thermal temperature of concrete wil change through comparison of theoretical data and field data.
