本文对每半幅为3车道,桥面宽16m,桥梁悬臂段、合龙段的施工技术要领和线形控制技术要领进行了论述,并对合龙时张拉方式对线形及梁体应力的影响进行了有限元计算分析,探讨了大宽幅连续刚构桥梁施工技术。
In this paper, the construction technique of main span and cantilever section of bridge with 3 lanes per lane and width of 16m is discussed, and the main points of the technique of linear control are discussed. And the influence of tensioning on the linear and beam stress during closing is limited Element calculation and analysis, discusses the wide-span continuous rigid frame bridge construction technology.
