摘　　要：本文以郑州地铁5号线桩基托换工程为依托, 根据监测数据, 得到新旧结构最大位移点的位置, 分析得出托换过程中结构的位移变化特点.本文的研究成果可为类似桩基托换工程提供参考.Based on the pile foundation underpinning projeet of Zhengzhou Metro Line 5 and the monitoring data, this paper obtained the position of the maximum displaeement point of the old and new struetures. The eharaeteristies of the displaeement＇ variations in the strueture during the proeess of underpinning were analyzed. The researeh results of this paper eould provide referenees for other similar pile foundation underpinning projects.
