The Finite Element Analysis of the End Anchorage under Larger Prestressing Load in Rehabilitation Engineering
Anchorages are the most important structure in the bridge’s rehabilitation engineering under external prestressing load, whose stress distribution is complex, it is necessary to carry out a detailed and careful structure analysis of anchorages. The inspection and strengthening design of an extra-large Bridge in Dongpu of Guangzhou City was taken for the background in the paper, the longitudinal stress, transverse stress and vertical stress of the end anchorage were given before and after adding concrete block, through finite element analysis of the end anchorage under larger prestressing load and the results of calculation of the anchorage were analyzed, it was showed that the strengthened effect of the end anchorage had been very obvious after concrete block was added. At the same time it was found that there were still some deficiencies on the end anchorage after concrete was added and the suggestions of the local strengthening of the end anchorage were proposed. It is helpful and referenced for the design of similar anchorage.
