摘要
通过对某铁路高墩水化热温度场实测实验及数值分析的对比,研究大体积混凝土桥墩水化热温度场的特点,验证数值分析的精度,并提出防止水化热温度梯度而导致的墩身早期开裂的有效工程措施。
According to the comparison of the experiment and numeric analysis of the temperature field of hydration heat at high piers of some railway,the paper researches the features for the temperature field of hydration heat at massive concrete bridge pier,proves the accuracy of the numeric analysis,and points out the effective engineering measures to prevent the cracks on piers in earlier period caused by the temperature gradient of the hydration heat.
