摘　　要：对中国桥梁规范JTG和英国桥梁规范BS5400中结构验算部分进行了比对和分析,并选取在建海外桥梁工程,采用中英两国规范分别对30 m跨径简支工字梁进行验算比较,比较结果显示,中国规范的公式和方法更为简洁,便于工程设计,控制要求比英国规范严格。In this article, by comparing the checking part of the Chinese code JTG and British code BS5400, a specific project undergoing overseas is selected as a calculation model. In this project, the 30 m span simply supported PSC I girder is adopted as the mainline structure. The results show that the checking methods and equations from JTG are more concise than those from BS, thus the YrG code is relatively more directly for designing, also, the checking criterion of JTG is more severe.
