The main stadium of Hangzhou Olympic and International Expo Center is a hybrid steel structures which is composed of large cantilever space pipe truss and single-layer suspended lattice shell structure. Based on the structural characteristics and construction difficulties of the steel structure, research on the advantages and disadvantages of three kinds of installation methods for the construction process is focused on. At the same time, the key construction technologies and difficulties for the sectional assembling, sectional installation,high altitude connection,closure technology and support frame unloading, etc, are discussed in detail in this paper. FEA simulation analysis on the whole construction process shows that the construction technology is efficient and rational. As a result, the engineering quality and construction safety are guaranteed.
