基于Matlab对古塔变形趋势探究的数学模型

Exploration of ancient pagoda deformation tendency based on Matlab mathematical model

通过对具有上千年历史某古塔的不连续4年数据的分析和处理,以曲线拟合为基础,对变形观测数据进行分析处理,求解出每层中心坐标。利用中心坐标,计算古塔倾斜度、曲率、扭曲夹角等指标分析古塔变形情况,用灰色预测法建立古塔的倾斜度的预测方程模型。

Data has been collected for 4 discontinuous years on an ancient pagoda. Based on curve fitting, the obtained de-formation data was analyzed and processed and the coordinates of the center was made out. Tilt, curvature, twisting angle of ancient pagoda were calculated to analyze the deformation of the pagoda. Finally, prediction equation model for forecasting the lean of the pagoda was established by use of grey prediction.
