摘要
根据京津城际轨道交通工程廊良路(32+48+32)m连续梁合拢段施工的实际情况,采用先边跨、后中跨的合拢方案,完成两次体系转换,介绍了连续梁合拢段施工方法和施工质量控制,为以后同类连续梁的合拢施工提供了参考。
In the light of the practical conditions of the construction of the closing sections of the 32＋48＋ 32 m continuous girder of the Beijing-Tianjin Inter-municipal Track Transit Project, the closing plan of closing the side-span first and closing the mid-span second was adopted, with the shifting of different systems performed twice. The construction process for and the quality control of the closing sections of the continuous girder are dealt with in the paper, which may serve as a useful reference for the closing construction of other continuous girders of the same type.
