摘要
通过对西张村大桥空心薄壁墩水化热温度测试结果的分析,阐述了薄壁墩混凝土在水化热影响下温度的分布规律及温度随时间变化规律,提出了防止温差过大而引起混凝土开裂的一些措施,为薄壁墩施工提供有益的参考。
According to the result of the hydration temperature of observation of hollow-thin pier of Xizhang Village Bridge,the temperature distribution regulation of hollow-thin pier concrete influenced by hydration heat and the temperature changing regulation affected by time are dis- cussed, pointing out measures to prevent concrete cracks caused by great temperature difference.The beneficial reference for construction of hol- low-thin pier are supplied.
