五里店立交桥箱梁变形鉴定分析

以五里店立交桥箱梁工程为例，针对箱梁变形和裂缝，通过对箱梁的截面尺寸、线形、裂缝等的检测，建立箱梁的理论分析模型，对附加应力对箱梁的影响、箱梁的承载力等进行了验算，验算表明，该箱梁在加固后可继续使用。

Evaluation analysis of box girder deformation of Wulidian Bridge

Taking the box girder project of Wulidian Bridge as an example,aiming at the box girder deformation and cracks,through the box girder cross-section dimensions,linear,cracks and other testing,established the theoretical analysis model of the box girder,analyzed the additional internal forces of the box girder,and calculated the carrying capacity of the box girders etc.The calculating shows that the box girder could be renewable used after reinforcement.
