中文摘要：

概括传统工程进度跟踪存在的缺点，分析工程进度信息化的优点及运用VML、SOAP等实现工程进度管理系统的重点与难点，提出进度管理系统的总体框架和数据交互模型，并给出VML在基于B／S架构的工程进度管理系统中应用的解决方案，最后给出系统在铁路建设工程中隧道与桥梁的应用实例及部分关键技术。

英文摘要：

This paper summarized the shortcomings that exist in the progress tracking of traditional project;The advantage on the informationization of projects progress is analyzed and pointed out;Relevant keystone and difficult technology is explained, such as VML, SOAP, DOM and so on;And the whole framework and interactive data model in the management system of project progress were brought forward ; Then the management system of project progress application solutions which VML is based on the B / S structure is proposed;At last the practical application of the tunnels, bridges and some key technologies for railway projects were given out.
