摘要
公路工程桥涵台背属于刚柔过渡区域,其在行车品质中占有重要地位。研究结合具体工程项目,分析桥头跳车产生的机理主要是由“错台”或“附加坡度”存在导致的,总结出台背回填土沉降主控因素,从设计、施工、材料等方面得出了桥头变形敏感因素。
The back of highway bridge and culvert platform belongs to rigid and flexible transition area,which plays an important role in driving quality.Combined with the specific project,the mechanism of bridge head jump is mainly caused by the existence of"wrong platform"or"additional slope",the main control factors of backfill soil settlement are summarized,and the sensitive factors of bridge head deformation are obtained from the aspects of design,construction and materials.
