摘要
运用有限元分析,结合现场实测,对塔梁固结斜拉桥横梁预应力缺陷进行了研究,分析了索塔下横梁预应力张拉效果不佳的原因,并提出了解决问题的具体方法,可供类似桥梁设计和施工参考借鉴。
Combined with actual measurement on the spot, it studies the defect of crossbeam prestress of cable-stayed bridge with tower beam consolidation using finite element analysis, analyzes the causes of bad stretching effect of crossbeam prestress under cable tower, and proposes concrete methods to solve the problem, in order to offer a reference for the design and construction of similar bridges.
