| 摘 要： | 某桥异形板区域单点支承的异形板结构,由于受各种综合因素影响,桥梁基础产生不同程度的沉降,从而对异形板整体受力状态产生影响,造成中横梁抗剪能力不足。对该横梁受力进行分析,为改善其受力状态,提高加固措施(或材料)的利用效率,运用主动加固的理念,创造性地采用"测力可调支座"结合钢盖梁支顶(π形钢盖梁支顶),较好地解决了异形板桥梁加固的难题。

| Abstract: | The different extents of settlement happen in the bridge foundation because of the irregular slab structure of the single-point supporting in the irregular slab area of a bridge influenced by various factors so as to influence the integral stress state of irregular slab and cause the insufficient anti-shearing capacity of the middle crossbeam.The article analyzes the stress of this crossbeam and enhances the utilization efficiency of reinforcing measures(or materials) in order to improve its stress state.The application of activereinforcement idea and the innovatively use of the "dynamometer adjustable support" plus steel cappingbeam roof support can better solve the difficulty of irregular slab bridge. |
