摘　　要：当前,国内外在建筑物纠偏技术方面研究还十分匮乏,大都依靠工程经验。针对此种现状,以实际工程项目——某新建工厂料仓为背景,进行了现场监测和实验,且利用有限元软件ANSYS进行了较为系统的分析,模拟顶升过程中各工况对顶升效果影响,最终得到了上部结构、托换梁、基础以及地基协同工作情况,并指出了最不利的工况,并以此为依据有效地指导了该工程的纠偏工作,实践表明该方法达到了良好效果。这为今后进一步研究纠偏方法,合理确定纠偏方案以及合理设计的托换系统,提供有效方法和理论指导。At present, domestic and foreign studies on building rectification technology are very scarce, and mostly depend on engineering experience. In view of this situation, based on the actual project———a new plant silo as background, the field monitoring and experiments are made, and through a systematic analysis by using the finite element software ANSYS, the simulation of lifting process and lifting effect is realized, and finally the collaborative work conditions for the upper structure, foundation and foundation underpinning beam are obtained and the most adverse conditions are pointed out so as to effectively guide the rectification work. The engineering practice shows that this method achieves good results and provides effective method and theory guidance for fur-ther research on correcting method, choice of a reasonable correction scheme and reasonable design of underpin-ning system.
