预应力混凝土连续梁桥支座更换及梁体复位施工监控研究

Construction Monitoring for Bearing Replacement and Girder Adjusting of Prestressed Concrete Girder Bridge

对预应力混凝土连续T梁桥苏洋大桥进行了支座更换和梁体复位施工。通过对施工过程中的梁体位移和梁体应力(应变)进行实时监控,苏洋大桥的支座更换和梁体复位施工安全得到保证,工程施工在不中断交通的情况下顺利完成。通过对大桥维修加固后的桥梁线形进行测量,证明了大桥的支座更换和梁体复位施工完成了既定目标。

The construction, the bearing replacement and the girder adjusting are carried out for the prestressed concrete bridge, Suyang Bridge. The displacement and the strain of the girder are measured timely. According to measurement result, the safety of the construction for the bearing replacement and the girder adjusting is guaranteed. The construction of the project is finished without traffic interruption. Finally, according to the figure measurement of the bridge after the construction, the desired result of the construction is testified.
