摘　　要：国家图书馆工程采用巨型钢桁架结构体系,依据工程结构特点,确定了"地面拼装、整体提升"的总体施工方案,通过计算、分析、优化,最终确定共布置28个提升吊点,采用提升油缸、适当提高安全系数以及位置同步与载荷分配相结合等控制措施应对提升施工中的难点,确保了提升施工安全顺利完成,达到了预期目的。According to the the structural characteristics of the project, a general construction plan of ＂ground assembly and integral lift＂ was established for the huge steel truss structure system of the National Library Project. By calculation, analysis and optimization, it was finalized that 28 suspension points would be arranged, and some controlling measures, such as, adopting lifting hydraulic cylinder, raising the safe factors properly and synchronous position as well as load distribution etc. were taken to settle the difficulties in the lifting construction, by which the lifting construction was completed safely and smoothly, reaching the anticipated goal.
