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.
