Rsearch on Load Adaptability of Existing Hollow Slab Bridge of Ji-Qing Highway

Abstract

Throughout the reconstruction and expansion process of the Jinan and Qingdao Expressway, there is a need for the existing Bridge to be demolished first and then reinforced for a better utilization. In order to better evaluate the load capability of the Level 1 lane, the load ability of the Seven-Ministry loads adaptability model and the current Ji-Qing traffic model, this paper examines three models of the load adaptability of existing small span Bridges. The load adaptability of the three load models on the old bridge of Jiqing existing line is analysed by comparing the bearing capacity level of the three load models in the three spans of 5m, 8m, and 13m of the hollow slab bridge.
