摘　　要：通过对开封铁塔近几年的实测数据分析研究，提出了确定铁塔各层中心坐标的计算方法，分析研究了该铁塔的倾斜、弯曲、扭曲等各种形变。根据实际测量数据计算分析其形变数量，对该铁塔的倾斜形变进行预测，为管理部门制定保护措施提供依据。In this paper, through the analysis of the measured data of Kaifeng Iron Pagoda in recent years, the calculation method of determining the center coordinates of Iron Pagoda was put forward and various deformations including tilts, bends, and twists were analyzed. Through calculation and analysis of the deformation quantity according to the measured data, tilt in Kaifeng Iron Pagoda is predicted, and the basis to formulate measures of protection for the management is provided.
