桥梁盆式支座更换实例

Practical Example of Replacing Potted Support of Bridge

在某连续箱形桥梁施工过程中,由于施工过程疏忽,造成6个盆式支座发生不同程度的倾斜偏位,其中倾斜最大处使盆式支座上钢板高差达到35mm,大大超出规范允许值,并使梁体的受力无法与设计吻合,需要通过对支座进行更换,使支座受力符合设计要求。该文介绍了桥梁盆式支座更换实例,可供类似工程参考。

In the course of constructing a continuous box beam bridge, the inclined deviations of six potted supports happen in the varying degrees because of the carelessness in the construction, in which the maximum inclined deviation makes the height difference of the steel plate on the potted support reach 35 mm, which greatly exceeds the permitted value of the standard and make the bearing of the beam unable to match with the design. It is required to replace the support to make the support bearing comply with the design requirement. The article introduces the practical example of replacing the potted support of the bridge, which can be provided to the similar projects for reference.
