摘要：
Because the stress concentration usually appears in the plate corner or discontinuity zone, it is necessary to optimize design for local plate of steel anchor beam bearing huge cable force. Based on 3D elaborate finite-element method, the stress distribution of steel anchor beam of cable-pylon composite anchor structure was analyzed. The results showed that the steel anchor beam of cable-pylon composite anchorage structure was safe and reliable, the application of the vertical stiffened plate of the side plate in anchor box and the middle diaphragm efficiently improved the force state of the steel anchor beam, on the other hand the stress conditions of the concrete pylon was more ideal when the steel anchor beam was within the boundary condition of one end of anchor beam fixed and the other end with sliding support.
