摘要
通过对桥梁后加承台大体积混凝土水化热的仿真分析,研究了温度场在承台内部分布和随时间变化规律,结果表明理论分析是可信的。分析了梧州云龙大桥加固工程,说明分层浇筑可以有效降低混凝土内部最高温升。并给出了大体积混凝土裂缝控制的一些措施。
Hydration heat simulation analysis is conducted for massive concrete of bridge＇s post cushion cap to study the distribution of temperature field within the cushion cap and its variation law as the time passes by, which demonstrates that theoretical analysis is reliable. The analysis on reinforcement engineering of Wuzhou Yunlong Bridge indicates that placement layer by layer may effectively lower the max. temperature rise within concrete, and proposes some measures to control the occurrence of cracks on massive concrete.
