摘　　要：在高速和重载的情况下，铁路既有桥梁需要重新检定其使用状态。根据现行《铁路桥梁检定规范》，用ＦＯＲＴＲＡＮ语言编制了常见桥型的检算程序，用ＶｉｓｕａｌＢａｓｉｃ设计了人机界面，形成了功能完善的既有桥梁检算系统。介绍了系统的功能、结构、开发系统时遇到的问题和解决方法。In the instance of high speed and heavy load,the using conditions of the existing railway bridges need to be rated again.According to the active rules of the railway bridge rating,the paper plaits the rate program of common bridges with FORTRAN language,designs the interface with Visual Basic, and then forms an existing railway bridge rating system with perfect functions.The paper emphatically presents the contents of the system, such as the functions strucure composition, and problems that we may encounter during the development,and how to conquer them.
