| 摘 要： | 以苏通大桥连续刚构墩顶现浇箱梁为例,对其水化热效应进行了分析,得到了箱梁水化热阶段温度应力的分布规律,结果表明水化热效应导致的温度应力是不容忽视的,并提出控制温度裂缝的有效方法,对早期混凝土裂缝控制具有一定的参考价值。

| Abstract: | Based on analysis of hydration heat effect on the cast-in-place segments on the piers' top of the continuous rigid-frame of Sutong Bridge,the distribution regularity of temperature stress is expounded.The results show that temperature stress shouldn't be neglected.Several effective measures are presented for controlling temperature crack,which can be consulted for early crack controlling. |
