文章结合罗天乐连续刚构桥施工实例，运用有限元模型对该桥0#块混凝土浇筑施工过程中的温度场变化情况进行了数值模拟分析。结果表明，0#块混凝土内部最高温度及最大内外温差计算值与实测值吻合较好。
文章結閤囉天樂連續剛構橋施工實例，運用有限元模型對該橋0#塊混凝土澆築施工過程中的溫度場變化情況進行瞭數值模擬分析。結果錶明，0#塊混凝土內部最高溫度及最大內外溫差計算值與實測值吻閤較好。

With the Luotianle Continuous Rigid Frame Bridge construction as the case, the article applied the finite element model to conduct the numerical simulation analysis on the changes of temperature field in the process of 0# Block concrete placement construction. The result showed that the internal maximum temperature and the maximum calculation value of temperature difference between inside and outside of 0# Block concrete matched well with the actual measured value.
