Research And Practice Of Digital Protection Technology For Historical Buildings

As a cultural carrier,historical buildings embodies the humanistic characteristics of different periods and different regions,and contains profound cultural heritage.They are also the best part of the wisdom shared by the Chinese nation for thousands of years.As an actual example from ancient times to the present,historical buildings contain precious values that are of great significance to the inheritance of my country’s historical culture.Due to the backwardness of previous information-preservation methods,construction information files have only been recorded to a small extent.Most of the information has been lost in the long history.Thus,the "authenticity" and construction information carried by the historical buildings cannot be maintained during the repairing and protecting processes.Besides,without the information,the protective action may cause irreversible secondary damage.In order to solve the problems of information loss,secondary injury and other issues,digital protection technology was born in line with the development of science and technology,which provides a new method for the protection of historical buildings.Compared with traditional protection methods,digital protection has the advantages of fast efficiency,high precision,true reduction,and preventable simulation.The application of digital technology can comprehensively improve the protection of historical buildings.Therefore,based on the analysis of various digital technologies and their applicability of protection,we used digital technology including virtual restoration and simulation analysis to study the national protection unit Xujiaqiao General Office of Ming Dynasty(in Lingling District of Yongzhou City,Hunan Province).The main content is as follows:1.Building information model(BIM)technology has been used to establish a model for the virtual restoration of historical buildings.A database of the component was constructed.By selecting the real layout,structure and building materials,the Xujiaqiao general mansion was virtually restored,which provides a reference for the later repair and protection work.2.Based on the current situation of the historical building,the software simulation was used to analyze the local enthalpy humidity and temperature of the general mansion.The optimized requirements for comfortable living was simulated.3.Because the indoor environment can no longer meet the requirements of modern living,thus,Xujiaqiao General Mansion was implicitly modified.By using insulation materials and cooling heating equipment,suitable hidden improvement plan was obtained by numerical simulations.
