摘要
U型桥台是公路桥梁下部结构常用的构造,在工程实践中,常常出现开裂,依据规范的有关条文,给出了常用桥台的构造内坡比的建议值,给出了侧墙滑动面受限制的土压力公式,进一步提出了改善桥台受力和减小变形的设计方法。
U - Type abutment is a construction in common use for substructure of bridge. It frequently produces crack in practice of engineering. From clauses related to specification, the paper gives the recommendation value of ratio of internal slope in structure of common abutment and also the formula for earth pressure for restricting the slip plane of lateral wall, further raises methods for improvement of load bearing of abutment and reduction of deformation of it.
