摘要:
顶进施工技术在下穿铁路框架桥中有着广泛的工程应用。随着铁路等级、行车速度、安全防护级别等标准的提高，为确保施工期间铁路行车安全，设计需增强铁路加固防护工程，从而导致其造价大幅提高。文章通过选取三条不同铁路线的下穿铁路顶进框架桥工程实例，对比分析各项工程经济指标，提出铁路加固防护工程在控制整个框架桥工程造价中的重要影响因素。从而为合理控制框架桥投资提出建设性意见，也为今后此类工程的限额设计和投资估算提供参考依据。
Abstract:
The jacking construction technology is widely applied on the frame bridge in the underpass railway. With the improvement of rail classification,running speed and safety protection level,railway reinforcement and protection project should be strengthened to ensure the safety of railway traffic during the construction. Thus the cost of the project is greatly increased. By selecting three cases of jacking frame underpass railway in this paper, various indexes of engineering and economics are compared and analyzed, and the important factors influencing the railway reinforcement and protection engineering in controlling the whole jacking frame project cost are put forward. Therefore, the constructive suggestions on reasonable control of the investment in the jacking frame are put forward, and the reference bases are provided for the quota design and investment estimation of this kind of project in the future.
