Abstract：
Hydraulic climbing formwork was used for construction of core tube structure in the super-high Beijing Greenland Center project, to guarantee the structural safety of core tube wall. Meanwhile, a series of measures were prepared in advance against construction difficulties, such as connection of steel bars in horizontal component, variable cross-section of wall, base of truss layer and climbing of tower crane, etc., and advance control of fire and safety at high altitude were also adopted. These measures realized favorable construction effects.
