中国小跨径高速铁路桥梁设计与建造的近期发展状况
摘 要
高速铁路（HSR）已经成为中国国家交通运输网络中一个至关重要的组成部分。随着高速铁路的建造发展，许多标准的小跨径桥梁作为基础设施的一部分被建造完成。本文的重点在于用一些典型的简支梁桥和连续梁桥，来说明在过去的十年里中国的高速铁路建设发展的有多快，有多成功。本文会简要回顾中国高速铁路发展的历史，并讨论一些中国高速铁路发展中出现的问题。讨论两种典型跨径桥梁的设计理念及建造规模，包括上部结构,下部结构以及桥上辅助设施。另外将会讨论不同的建造方法。

ABSTRACT
High-speed rail (HSR) has become a vital component of the national transportation network in China. A large number of standard short-span bridges were constructed as part of the infrastructure associated with the HSR development. The main focus of this short review is to showcase how the fast HSR construction in China during the past decade was achieved by using typical simply supported bridges and continuous beam bridges. This paper provides a brief historical review of the HSR development in China along with emerging design issues. Design concepts and structural dimensions of two typical spans are dis- cussed, including the superstructure, substructure as well as the auxiliary facilities on the bridge deck. Different construction methods were also discussed.
