| Guangzhou Aircraft Maintenance Company Facilities (New Baiyun International Airport) are the national, provincial and city key projects invested by China Southern Airlines Guangzhou Aircraft Maintenance Engineering Company Ltd. (GAMECO). It is consisted of No. 10 Hangar, No. 12 ground maintenance。No. 10 Hangar is the core part, and can satisfy the requirement of the maintenance of three broad body aircrafts and the print of one broad body aircraft simultaneously.The structure of No. 10 Hangar is the large span spatial steel truss system, continuously spanning 100m, 150m and 100m respectively. The Computer-controlled Integral Lifting Erection is adopted in the construction of the main part of the steel roof, which cover 250m*76m and weighting 4500t.This thesis aims at analyzing and solving the technical problems in the integral lifting of No. 10 Hangar. The main works are concluded as follows:Firstly, determining the construction sequences of the integral erection and designing the pre-deformation values of large span members in order to avoid too big deflections; Secondly, checking the strength and stability of all the members and insuring them safe during the lifting construction. The trusses in lifting is different from that in service, such as non-uniformly displacement increase and the segmentalized lifting in the truss B; Thirdly, designing the accessorial members used in the construction process. They include lifting platform at the top of the columns, reinforcement for members in lift position and lifting lug etc.For large span structures, construction method and construction design are as important as the structural design. During the construction process, the stability and the strength of all the members need to be considered sufficiently.
