摘要
介绍西安北站屋盖结构单元吊装方案,深入剖析屋盖吊装过程中的力学问题,提出基于一体化模型的施工全过程分析方法。该方法探究了施工过程中临时支撑、屋盖网架以及结构支撑体系的内力及变形变化情况,对西安北站的施工全过程进行跟踪分析,分析结果可为工程的顺利实施提供技术支持。
The construction scheme of New Xi’an Railway Station is introduced firsly.Then possible mechanical problems during construction are discussed in detail.To solve these problems,an analysis procedure based on an integrated model which comprises all the permanent and temporary structures is proposed.Through this integrated model,the deformation and stress distribution of the brace system,steel roof structure and columns during construction can be monitored and traced precisely.The obtained results are helpful for the practical construction.
