摘　　要：结构的吊装多数采用一台或两台吊机进行吊装，吊装过程简单，在实际施工控制方面也相对简单。但在海洋工程建造方面，结构物的尺寸和重量都很大，单台和两台吊机吊装已经不能满足要求，很多时候会采用4台吊机进行吊装。论文对4台吊机抬吊结构物中的风险因素：钩头力的不确定性、重心的不确定性、极限工况等方面进行分析，对整个吊装过程进行探讨，并采用分析软件SACS对其进行模拟，使得吊装模拟计算与吊装过程达到了很好的吻合，很好地指导了现场施工，并为后期4台吊机吊装提供了技术支持。It usually needs one or two cranes to lift a structure, where the lifting process and lifting control is very simple, in practice. But in ocean engineering fabrication, both size and weight of a structure are huge, only single or two cranes lifting cannot meet the requirements, and four cranes will be adopted most of the time. In this paper, risk factors in lifting structures, including uncertainty of hook force, uncertainty of center of gravity and limit condition are researched and analyzed. Then whole lifting process is discussed. Software a
