本文通过工程实例,主要介绍了先简支后连续桥梁结构施工工艺特点及其施工质量控制方法。该桥梁结构有连续梁桥的整体受力特点,但是相对连续梁桥它具有施工方便占有机械设备少及其工艺简单的特点。先简支后连续桥梁结构对地质条件复杂的地区和同一座桥梁基础坐落在力学性质截然不同的持力层上的情况十分适用,其连续段每联的长度根据设计多跨桥的孔数和桥梁平曲线半径的大小来确定,一般连续长度控制在200米以内。
In this paper, through the engineering examples, the paper mainly introduces the construction process characteristics and construction quality control methods of the first simply supported continuous bridge. The bridge structure has the characteristics of the continuous beam of the whole force, but it has a relatively continuous construction of the beam bridge less possession of mechanical equipment and its simple process characteristics. The first simply supported by the continuous bridge structure of the geological conditions of complex areas and the same bridge foundation is located in a very different mechanical properties of the holding layer is very applicable to the length of each of its continuous section according to the design of the number of holes and multi-span bridge Bridge curve to determine the size of the radius, the general continuous length control within 200 meters.
