Analysis of Load Effects and Load Lifting Effects of Solid Slab Bridges
Due to the constraints of the construction level,natural environment erosion,material deterioration,and other factors,the service performance of early-built bridges is difficult to meet the demands of increasing traffic volumes.According to investigation data of ordinary national highways in Xinzhou,Shanxi,based on the finite element simulation,this paper analyzed the structural response of solid slab bridges under the Highway-Ⅱ load and Vehicle-15 load and the load lifting effect of carbon fiber cloth reinforcement.The results showed that using carbon fiber cloth to reinforce the early solid slab bridge of Vehicle-15 load was difficult to meet the requirements of lifting the load to Highway-Ⅱ grade.
