目前预应力混凝土连续梁桥的施工方法已经达到相当先进的水平,无论是城市桥梁、高架道路,还是跨越宽阔河流的大桥,预应力混凝土连续梁都越来越多地发挥了它的优势,尤其是应用悬臂施工方法后,加速了它发展的步伐。本文介绍了大治河连续梁桥的设计,这是一座采用挂篮悬臂浇注法施工、三跨变截面设计的连续梁桥,对设计计算进行了比较详细的分析,得出了一些设计经验。
At present, the construction method of prestressed concrete continuous girder bridge has reached a quite advanced level. Whether it is an urban bridge, an elevated road or a bridge spanning a wide river, prestressed concrete continuous beams are more and more exerting their advantages, in particular Is the application of cantilever construction method, accelerated its pace of development. This paper introduces the design of Dazhihe continuous beam bridge, which is a continuous beam bridge constructed by hanging basket cantilever casting method and designed with three span variable cross sections. The design calculation is analyzed in detail and some design experiences are obtained.
