连续梁桥纵向偏移量设置

On the setting of longitudinal offset of continuous beam bridge

结合广州市轨道交通四号线市桥沥连续梁桥纵向偏移量的设置情况,重点介绍连续梁纵向偏移量的计算和设置,以弥补混凝土收缩徐变以及梁体温度降低引起的收缩量。

Combined with practical work of Shiqiaoli continuous beam bridge in No. 4 rail transit line of Guangzhou the setting situations of longitudinal offset are mentioned. The calculation and practical setting method of longitudinal offset of continuous beam are mainly introduced in order to compensate the shrinkages caused by temperature reduce, concrete shrinkage and creep.
