Abstract:The tube-truss on-site assembling and hoisting of the main stadium in Guiyang Olympic Sports Center was expounded. The main problems were the influence of the construction site on the assembly construction, as well as the various styles of the truss and the high-precision requirment of the design that result in the difficulty in the assemble works. According to the conditions above, the arrangement of the assembly construction, the construction principle and the precision control measure in the assembly construction were described.

Keywords:pipe truss; on-site assembling; assembly frame; precision control
