【摘要】 歧江河大桥主桥为双塔单索面部分斜拉桥,针对其结构特点和技术标准,制定了施工阶段的施工方案和施工流程,明确了各施工阶段典型受力状况。通过应用结构分析程序对各施工阶段进行总体结构静力仿真分析,验证了施工方案的可行性和结构设计的安全性,并将计算结果与同等跨径的连续梁桥和斜拉桥进行了对比分析。更多还原

【Abstract】 The main bridge of Qijiang River Bridge is an extradosed bridge with double pylons and single cable plane. For construction of the main bridge, the construction schemes and procedures were established, and the typical stressing conditions at various construction stages were defined in advance in accordance with the structural features of and the technical standards required for the bridge. In this paper, the static simulation analysis of the overall structure of the bridge at the various construction stages is conducted with the structural analysis programs, the feasibility of the construction schemes and the safety of the structural design are verified, and further, the calculation results are analytically compared to those of the continuous girder bridge and cable-stayed bridge with same span length.更多还原
