Investigation of Crack Causes and Structural Limit State Check of Active Hollow Slab Bridge


Ting Ye, Liangpeng Nie, Pengsheng You


Aiming at the cracks of the hollow slab bridge in service, a special on-site traffic survey is carried out. Based on the survey, the limit state of the hollow slab bearing capacity is checked, and the internal and external causes of the cracks in the hollow slab are analyzed to provide subsequent reinforcement treatment in accordance with.
