广渠路跨丰双铁路分离式立交桥顶推施工与监控技术

广渠路跨丰双铁路分离式立交桥连续2跨跨越电气化繁忙铁路,为把对既有线路正常运营的影响降到最低,确保施工期间的行车安全,项目采用顶推法施工。结合项目特点,通过对施工过程关键点的介绍以及对监控内容和方法的探讨,为今后类似工程的施工提供现场施工经验。

Incremental Launching Construction and Monitoring Technology of Separate Overpass of the Guangqu Road Overcrossing Fengshuang Railway

The separate overpass of Guangqu Road overcrossing Fengshuang Railway goes over two electrified busy railway in a row.To reduce the effect on the normal operation of existing routes as much as possible,the project adopts the incre-mental launching method to ensure the safety during construction.According to the features of the project,the key points in construction process are introduced and the study is made on the monitoring content and method,which provide field con-struction experience for the future similar engineering.
