摘要

研究目的:根据时速客运专线铁路在构造、受力、耐久性、检查功能及关观等方而的特点，设计出合理、适用的桥台

研究方法:结合桥台在功能、刚度及强度方而的要求，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。

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.
