Hydration Heat Simulation Analysis on Concrete for Bridge's Cushion Cap

ZHANG Yu-xin,GOU Ji,LIAO Chen-feng(College of Civil Engineering and Architecture of Guangxi University,Nanning 530004)  
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.
