Abstract

Research purposes: The cable—girder anchor gone of long span steel cable—stayed bridge is the key zone where bears giant cable forces with the complicated load—bearing situation．It is hardly to get the actual stress distribution and the mechanism of the stress transferring only by FEM analysis．Based on the static load test to the cable—girder anchor zone of the Huangpu Pead River Bridge．this paper researches the stress distribution and the mechanism of the stress transferring of the anchor—box type cable—girder anchor structure．

Research conclusions: The design of the anchor—-box test model for the Huangpu Pearl River Bridge is reasonable and the model can reflect the actual mechanical behavior of the bridge．The anchor—box type cable—girder anchor structure can transfer the stress smoothly and safely and it meets the functional requirement of the long span steel cable. Stayed bridge。
