摘要
以南方某混凝土预应力刚构大桥为背景,对混凝土徐变理论以及该理论在桥梁预拱度设置中的应用进行了研究,并利用GQJS和桥梁博士软件,计算了该桥梁施工的预拱度。算例分析表明徐变对预应力混凝土连续梁桥变形的影响均不容忽视。
In this paper, for the design and construction of a pre stress concrete bridge in south the concrete creep theory and the application on the pre-camber of pre-stress bridge are researched. The pre-camber of LiDong Bridge are calculated and analyzed by Dr Bridge and GQJS. The result shows that the concrete creep affect the bridge pre-camber so much that can＇t be ignored.
