Combining an example of an approach bridge engineering of a marine terminal, this paper describes the mix ration design and demands of self-compacted concrete with big fluidity, high strength and micro-expansion and slow coagulation applied to the large & multiple-span concrete-filled steel tube arch bridge.It also expounds the construction method, technological process and construction process control for the concrete pumping. The application effect revealed that using the steel tube concrete and construction method described above, we can effectively avoid the common problems such as the concrete segregation, plugging pump, steel tube blasting, concrete unevenness or incomplete densification.
