古塔变形量的分析与研究

古塔由于长期受到自重、气温、风力等各种自然因素的作用以及地震、飓风等偶然因素的影响,会产生各种变形。文章根据某古塔一至十三层每层八个测量数据,建立非线性规划模型计算出各层中心点的坐标,利用平面解析几何的相关知识可计算出各层的倾斜角度、倾斜位移以及扭曲程度,最后根据中心点的拟合曲线计算古塔的弯曲程度即曲率,预测古塔的倾斜角度、倾斜位移、扭曲程度以及弯曲程度的变化趋势。

Analysis and Study on the Deformation Amount of the Ancient Pagoda

Due to the sell weight, temperature, wind and other natural factors for a long time, as well as the impact of earthquakes, hurricanes and other accidental factors, the ancient pagoda will produce a variety of deformation. According to each layer＇s eight measurement data from one to thirteen layers of one ancient tower, the author establishes , nonlinear programming model to calculate the coordinates of the center point of each layer, use the knowledge of the plane analytic geometry to calculate the tilt angle, the tilt displacement and the bending degree, and finally calculate the ancient tower＇s bending curvature according to the fitting curve of the center point, to predict the change tendency of the ancient tower＇s inclination angle, tilt displacement, twist ,rod bending degree.
