古塔往往具有悠久的历史,它对文化的传承和经济的带动具有重要意义。由于长时间承受自重、气温、风力等各种作用,偶然还要受地震的影响,古塔常常会产生各种变形,因此,我们有必要加以保护。我们试图通过对古塔倾斜、扭曲、弯曲等方面的研究进而对古塔进行保护。 Old pagoda often has a long history, which is of great significance to the inheritance of culture and the promotion of economy. Due to long time to bear weight, temperature, wind and other effects, incidentally affected by the earthquake, the ancient tower often have a variety of deformation, therefore, we need to be protected.
