摘要
本文对预应力连续梁桥上部构造施工中的挠度变形原因进行了分析,结合惠河高速东江大桥的施工经验对悬臂现浇施工中的施工挠度控制方法进行了研究,并提出了一些有效措施。
The causes of vertical deformation during constructing superstruction of prestressed concrete beam bridge are analyzed in the paper. With the experience of construction of Dongjiang Bridge, we study the deformation control of cast - in - place cantilever segmental construction. Some conclusion is drawn and some reference may be given to others.
