Study on the Load Test of Variable Cross-Section Box Girder Bridge

Abstract:

In order to study the load property of variable cross-section continuous box girder bridge, in this paper, the static and dynamic load test were carried on the main span for Xiaoqinghe super-large bridge in Shandong province. The main girder stress, deflection, impact coefficient, self-vibration frequency and the static and dynamic characteristics were analyzed, compared with the theoretical calculation to judge the safety of the bridge.
