铁路现浇箱梁高性能混凝土的配制与施工控制

Preparation and construction control of high-performance concrete of cast-in-situ box beam on railway

以某客运专线特大桥为工程依托,对铁路现浇箱梁混凝土的配制技术、原材料选择、混凝土性能、施工工艺及质量控制进行论述,提出了实现铁路工程混凝土高性能化的方法与控制要点,从而提高箱梁混凝土的耐久性。

Taking the extra bridge on the passenger special line as the engineering background, this paper discusses preparation technology of concrete of cast-in-situ box beam on railway, raw material selection, concrete performance, construction technology, and quality control, and puts forward methods and controlling points for improving high-performance concrete of railway engineering, so as to improve the durability of concrete of box beam.
