摘要
临时固结是连续梁与桥墩间具有桥梁支座支撑而采用的一种施工工艺。该文结合香榭丽大桥悬臂浇筑施工实例,分析计算了悬臂浇筑出现的不平衡力矩,并对该工程临时固结体系采用矩形截面偏心受压构件的正截面抗压承载力进行受力验算分析,并与传统的悬臂浇筑法进行了比较分析,提出临时固结设计的优点。
Temporary fixation is a construction technology applied in continuous beam and pier as bridge support. Combined with the case of cast-in-place cantilever construction in Champs Elysees Bridge, the imbalanced moment of cast-in-place cantilever is analyzed and calculated, the flexure compression strength of eccentric compression member of rectangular section is calculated and analyzed and, based on the analysis and comparison with traditional cantilever construction method, the advanta~,es of temporary fixation desim~ are nresented
