摘要
针对大型斜拉桥梁大体积混凝土施工中的温度裂缝难题,对济南黄河三桥进行了实例分析,通过采用仿真分析与跟踪监测技术相结合的温控体系,从而解决了大体积混凝土施工中由于内外温差过大而容易造成开裂问题,为今后斜拉桥大体积混凝土施工提供了经验。
In order to solve the problems of thermal stresses and temperature crack of mass concrete in the construction of large cable-stayed bridge,Yellow river Bridge No.3 in Ji＇nan was taken for example,prevention and control system of pre-numerical analysis and tracking monitoring was used to solve the cracking due to too large temperature difference between inside and outside during the construction of mass concrete,which provided experience for cable-stayed bridge in future.
