Cable-stayed bridge construction method
The invention provides a construction method of a cable-stayed bridge, belongs to the technical field of bridge construction, realizes integral pouring of a main beam and a bridge tower, is good in integrity and larger in bearing capacity, slowly and intermittently tensions stay cables to generate memorability, avoids stress change of the stay cables in the later period, and improves the construction quality of the cable-stayed bridge. When the stay cables are symmetrically tensioned, secondary dead load and any construction load cannot be acted on the main beam, the stress balance is improved, fine construction steps determine high-quality engineering, the safety performance of the bridge is improved, the service life is longer, and good economic benefits are brought to enterprises and the society.
本发明提供了一种斜拉桥施工方法，属于桥梁施工的技术领域，实现了主梁和桥塔一体浇筑，整体性好，承载力更大，缓慢间歇性张拉斜拉索使之产生记忆性，规避了后期斜拉索受力改变，对称张拉斜拉索时主梁不得作用二期恒载及任何施工荷载，提高受力平衡性，精细的施工步骤决定高质量工程，提高了桥梁安全性能，使用寿命更久，为企业、为社会带来了良好的经济效益。
