补齐了给定数据中的缺失数据，建立模型计算出古塔每层中心点坐标，给出了古塔倾斜变形、弯曲变形和扭曲变形的描述，建立模型并计算出古塔倾斜夹角和倾斜方向，计算古塔各层弯曲情况，计算出古塔各层之间扭曲角度的变化情况以及扭曲方向，对古塔4年观测数据情况进行分析，给出2014年古塔变形情况的预测方法。%The missing data in the data ifle is completed. The coordinates of the central points are computed out by using the mathematical model. The deformation of the old tower is described in inclination and twist and bend, the inclination angle and the inclination direction are given, the bending condition and the twist angle and the twist direction are also computed in this paper. The method is described about the old tower deformation forecast in 2014 according to the given data.
