摘　　要：以某市X型钢结构人行立交桥主桥吊装工程为例,对其吊装全过程进行了阐述。双机抬吊技术可使施工更加安全,保证建筑结构的稳定,同时表明在实际施工中,机械及构件布置、测量监控及临时支架安装对吊装工程的精确度有较大的影响。Segment rotary hoisting method is widely applied in the large - scale component installation of the municipal engineering. According to the reasonable distribution of the weight of component, two crane finish the operation with the permission of the perform- ance during the construction. Takeing the whole process of X - shaped steel structure overpass of a city as an example, this article ex- pounds the whole construction process . Double machine lift technology can make the construction safer, guarantee the stability of building structure. At the same time, it also shows that in the practical construction , the greater effect is made on the accuracy of the installation of lifting project due to the arrangement, measuring and monitoring of machinery and components.
