摘    要:研究目的:根据时速客运专线铁路在构造、受力、耐久性、检查功能及美观等方面的特点,设计出合理、适用的桥台。研究方法:结合桥台在功能、刚度及强度方面的要求,确定桥台的构造类型;选择最不利荷载工况对桥台进行分析计算;并采用ANSYS程序对计算结果进行校核。研究结果:针对我国客运专线铁路所采用的整孔箱梁、组合箱梁,设计分别与之适用的矩形空心桥台、T形空心桥台。研究结论:矩形空心桥台、T形空心桥台在构造、受力、耐久性、功能上均能满足客运专线铁路的要求。路基-锥体-桥台-箱梁的检修通道设置简单、合理、便捷。

关 键 词:客运专线铁路  空心桥台  箱梁  耐久性  设计

Abstract:Research purposes: According to the characteristics of passenger dedicated railway line on conformation,load,durability,inspection function and appearance,the reasonable abutment is designed. Research methods:According to the requests of abutment on function,rigidity and strength,this paper confirms the type of abutment,calculates and analyzes the mechanical behavior of abutment in crucial load combination.And this paper also checks the conclusion by general FEM software ANSYS. Research results:Aimed at the simply supported box girder and the combined box girder of China passenger dedicated railway line,the rectangular hollow abutment and the T figure hollow abutment have been designed respectively. Research conclusions:The rectangular hollow abutment and the T figure hollow abutment meet the requirement of passenger dedicated railway line on conformation,load,durability and function.The setting of inspection passage from subgrade to cone to abutment to box girder is simple,reasonable and convenient.
Keywords:passenger dedicated railway line  hollow abutment  box girder  durability  design
