摘要: 以某V形支撑连续刚构桥为工程背景，对V形支撑0号块进行施工阶段分析和施工工况分析. 计算分析得到如下结论：V形支撑0号块在施工过程中的应力满足规范要求，其施工过程中的受力特性可供设计和施工人员参考；V形支撑0号块对顺桥向水平位移和竖向位移较为敏感，在施工过程中应该注意结构的位移监测；施工工况分析的结果与更为真实的施工阶段分析的结果存在一定差距，在实际的工程计算中应尽可能采用施工阶段分析.Abstract: With the V-shaped support continuous rigid frame bridge as the engineering background, the 0# block with V-shaped support was used for the construction stage analysis and construction working condition analysis. According to the analysis results, the following conclusions can be drawn: The stress of the 0# block with V-shaped support met the specification requirements during the construction process, and the stress characteristics during the construction process can be used for reference by designers and constructors. The 0# block with V-shaped support was more sensitive to horizontal displacement along the bridge and vertical displacement, and structural displacement monitoring should be paid attention to during the construction process. There is a certain gap between the analysis results of the construction working condition analysis and the more real analysis results of the construction stage, and the construction stage analysis is used as much as possible in the calculation and analysis of the actual project.
