47m T梁侧弯原因分析及控制措施

Causes of lateral bending of 47 m T beam and control measures

T梁的侧弯加大了梁片重心的偏位,不仅导致梁片在存放过程中难度加大,为吊装带来一系列难题。T梁的侧弯也会影响桥梁施工的顺利进行,若侧弯过大,则会导致梁体受力过大,导致安全事故。对47 m预制T梁张拉后出现的侧弯原因进行分析,提出相应的控制措施并指导施工,有效控制了施工质量。

The lateral bending of T beam increases the deflection of gravity center, which not only leads to the difficulty of the beam＇ storage, but also brings a series of problems for the lifting of the beam. Meanwhile, the lateral bending also affects the progress of bridge construction. If the bending is too large, it will cause adverse force to the beam, which is easy to lead to a serious accident. This paper analyzes the lateral bending of precast post- tensioned T beam, proposes corresponding control measures to guide the construction and control effectively the construction quality, hoping to serve as reference for persons of the same occupation.
