Model Test of the Auricular Plate Anchorage Zone of Hangzhou Bay Bridge

摘要

The 1:3 model of cable anchorage zone on Hangzhou Bay bridge steel box girder is tested in present study. The stress distribution, the force transformation route and the carrying capacity of the auricular plate and the steel box girder with the cable force multiple changing from 1.0 to 1.7, the inter force distribution and performance of bolts, and the rotation-ability are investigated. At last, the security and rationality of the anchorage zone are verified by the results of the model test and the finite element simulation. The results indicate that the cable anchorage zone of the main girder of the Hangzhou bay bridge is a perfect anchorage structure.
