京沪高速铁路泗河特大桥施工技术应用

Application of Construction Technology of the Sihe River Extra Large Bridge of the Jing-Hu(Beijing-Shanghai) High-speed Railway

京沪高铁是当今我国一次建设里程最长、投资最大、标准最高的高速铁路。结合参建的京沪高速铁路土建工程三标段泗河特大桥工程施工情况,从梁场规划设计、箱梁预制质量控制、制架梁进度控制、桥面系防护墙及预制构件质量控制、无砟轨道底座板及轨道板施工等方面对京沪高速铁路主要的施工技术创新应用情况进行了论述。

Jing- Hu（Beijing- Shanghai） high - speed railway is characterized by the longest mileage, the largest investment, the highest technical standard and non - staged completion at the present time in China.This paper gives an exposition of the application of the major technological innovations in construction of the Jing- Flu high- speed railway in terms of planning and design of beam fabricating yard, quality control of box beam precast, progress control of frame beam fabrication, quality control of bridge deck protective walls and precast elements and construction of non - stone fragment track bed plates and track plates according to the construction condition of the Sihe River extra large bridge un- der No. 3 bid for the civil construction of the Jing- Hu high - speed railway.
