摘　　要：针对扬州某科技园大跨度钢连廊高空整体提升施工进行模拟分析,提出实际吊装过程中可能出现的提升节点异步性问题,并针对提升节点不同步的问题,利用有限元软件SAP2000模拟分析连廊在提升过程中的随机异步性在提升、加固施工过程中的随机异步性,根据相关规范与实际施工状态对模拟参数进行取值,利用模拟数据得出吊点之间的随机偏移。分析结果可知:在实际施工过程中,应注重钢绞线的选择,对提升节点进行提升前预起拱等施工操作,同时精细化操作提升机械,尽力减少节点随机异步性的影响。A simulation analysis was conducted on the high-altitude overall lifting construction of the large-span steel corridor in a Science and Technology Park in Yangzhou.The actual problem of asynchronous lifting nodes that may occur during the actual lifting process was proposed.In response to the problem of asynchronous lifting nodes,this paper uses finite element software Sap2000 to simulate and analyze the random asynchrony of the corridor during the lifting and reinforcement construction process.From the above analysis results,it can be concluded that in the actual construction process,attention should be paid to the selection of steel strands,and construction operations such as pre arching before lifting the lifting nodes should be carried out.At the same time,the lifting machinery should be finely operated to minimize the impact of node randomness and asynchrony.
