Analysis of the Mechanical Behavior of Cable Tower during Self-Anchored Suspension Bridge Temporary Tower Anchor Self-Erection

The traditional construction technology of “beam first and cable later” for self-anchored suspension bridges affects the traffic under the bridge, making it difficult to meet the demands of modern bridge rapid construction. Therefore, this paper proposes a new type of temporary tower anchor self-erection technology. However, during the construction process, the stress mode of the tower will change, and the safety of the tower becomes the most important issue. Therefore, this paper takes a double-tower three-span self-anchored suspension bridge as the example background to discuss the influence rule of the structural parameters of the self-anchored suspension bridge on the stress of the tower. The influence law of various structural parameters on the cable tower stress is obtained, which provides a reference for future design and construction.
