| 摘 要： | 2013年全国大学生数学建模竞赛专科组C题提出某古塔由于长时间承受自重压力、气温变化、风力影响、雨水侵蚀等作用,偶然还要受地震、飓风等自然因素和爆炸、火灾等非自然因素的影响,都会产生各种变形,诸如倾斜、弯曲、扭曲等。为保护古代建筑——古塔,文物部门需适时对古塔进行观测,了解各种变形量,以制定必要的保护措施。拟结合观测数据给出了古塔中心曲线在三视图中的倾斜度和倾斜角、弯曲度和弯曲角以及扭转度和扭转角的数值矩阵。并得出结论:该古塔的倾斜角、弯曲角和扭转角都有逐年增大的趋势,说明该古塔变形的加剧,需要及时保护和维修。

| Abstract: | Combining with the observed data for ancient pagodas, the paper proposed the numerical matrix of the slope and the sloping angle of center curve, the bending and bending angle and the twist and twisting angle. It is concluded that the tilt angle, bending and torsional angles of the pagoda are increasing year by year. The study shows that the speed of deformation for the pagoda has been increased, it is necessary for us to take measures to protect and repair the ancient pagoda. |
