摘要
文章结合宜万铁路叶溪河大桥大体积混凝土施工,采用三维瞬态温度场,建立大体积混凝土温度场有限元计算模型,研究了温度场在承台内部分布和随时间变化的规律,并制定了一套完整的温度与裂缝控制方案,实践证明,采取控制措施后,施工效果良好。
Combining the bulk mass concrete construction of the Yexi river bridge in the Yiwan railway with the using of three-dimensional transient state temperature field,building the Finite Element Method model for bulk mass concrete temperature field ,then study the temperature field distribution and it＇s change law with time inside of the cushion cap, and made a package of comprehensive plans about temperature control and crevice control, Practice has shown that with the control measures, the effect of the construction come to be better.
