摘要
重庆大佛寺长江大桥为一座主跨 450 m的预应力混凝土斜拉桥 ,介绍了该桥主塔墩嵌固式承台大体积混凝土施工 ,分析了混凝土裂缝产生的机理 ,提出了防止温度裂缝产生的监控措施。
Chongqing Dafusi Changjiang River Bridge is a PC cable\|stayed bridge with a main span of 450 m.Construction of massive concrete of the built\|in pylon base of the bridge is described. The mechanism of crazing of the concrete is analyzed, and monitoring measures against the crazing due to temperatures are proposed.
