移动模架在瑞赣高速九岭高架上的应用

摘要

针对山区高速公路的特点，考虑到传统移动模架（ MSS）施工的经济跨径为50 m，随着跨径的增大用钢量急剧增加的现实，结合连续梁桥有两个反弯点的特点，引入移动模架“分块浇筑”设计理念，对九岭高架桥采用广州黄埔桥MSS62.5施工进行了探索，为今后移动模架在山区高速公路上的应用提供了参考。%For the characteristics of mountain highway,traditional Movable Scaffolding System( MSS)for the construction of the economic span 50 m,with the increase in long-span the usage of MSS steel increase,under the continuous girder bridge has the characteristics of two anti-bend point,the introduction of Movable Scaffolding System“partitioning casting”designing concept,explore the project construction of Jiuling rigid-frame bridge on the use of the Guangzhou Huangpu Bridge MSS62. 5,reference for the future MSS applications on the highway in the mountains.
