摘要
以千斤洞大桥30m预应力大空心板上部结构加固为背景,从构造特点、施工方法和关键技术等方面介绍了去梁增肋加固法的设计与施工特点。通过验证计算、模拟试验和监测结果,证明该新技术应用的成功,为去梁增肋法在空心板桥上部结构加固中的应用提供了经验。
Using 30M pre - stressed hollow slab integral reinforcement of the super - structure of Qianjindong Large Bridge as the example, to illustrate the design and construction features of the ＂less girder more rid＂ technique with respects to the structural characteristics, workmanship and critical technique. Finally to demonstrate the successful application of the ＂less girder more rid＂ technique provides important reference to the hollow slab superstructure reinforcement by verification calculation, simulation testing, and monitoring results.
