Key Construction Technology for Ultra Large Underground Reinforced Concrete Structure of Shanghai Tower

Based on Shanghai Tower underground structural engineering, the paper introduces a research on the large reinforced concrete structure construction, the formwork construction and the concrete works by a combined way of theoretical analysis and experimental study. A kind of concrete with high crack resistance under strong constraints has been developed, which has brought about a complete set of construction technology for the ultra-large reinforced concrete walls and studs. As a result, it meets the construction requirements, achieves the good results and provides reference for similar projects.
