高速铁路T构桥设计研究

Study on Design of T-structure Bridges of High-speed Railway

伴随着我国高速铁路的快速发展,预应力混凝土T构桥在国内桥梁结构中被广泛应用。本文主要结合某高速铁路客运专线T构的技术标准、结构参数、主要计算结果、工程数量等,对比分析高速铁路T构桥跨度选取、高跨之比、梁部结构刚度等问题,为今后类似高速铁路T构桥设计提供借鉴。

Along with the rapid development of high-speed railways in China,the prestressed concrete T-structure bridges are widely used in domestic bridge structures.This thesis mainly combines the technical standards,the structural parameters,the main calculation results and the engineering quantities of a high-speed railway passenger line T-structure,and then to comparing and analyzing the selection of span,the high span ratio and the structural stiffness of the girders of high-speed railway T-structure bridges,in order to provide a reference for the design of similar high-speed railway T-structure bridges in the future.
