以国内外最常见的16万m3液化天然气低温储罐施工为例，介绍了钢结构拱顶气升作业的工艺流程和操作要点，并对其最重要的平衡系统进行理论研究和量化分析，阐述了平衡系统的纠偏原理和纠偏能力，得出了平衡系统具有显著的抵抗水平倾覆的能力，但几乎不具有水平偏移和轴向偏转的纠偏能力，分析结果与工程实际情况相吻合，对今后顶升工艺设计具有一定的参考价值。

Taking installation of typical 160 000 m3 liquefied natural gas (LNG) tanks for exam-ple ,the process and operating key points of roof air-rising are introduced ,and the leveling system of roof air-rising was focused on the theoretical research and quantitative analysis .It elaborated the principles and abilities to anti-deviation of leveling system ,thus conclusionn was made that the leveling system has an outstanding ability to resist roof overturning ,and little ability to con-trol horizontal and circumferential displacement ,which is consistent with the actual situation ,so it's valuable to air-rising process design in future .
