Research On Environental Control Of Protection And Display Facilities For Brick Archeological Site

Under a long history,there is a large number of archaeological remains in China.Ancient tombs and brick or stone made buildings,which are mainly brick archeological sites,have suffered various diseases caused by environmental factors.With the public's attention to preventative protection,a large number of construction facilities such as exhibitions for various types of sites with the main purpose of protection,display,and research have been constructed.In the design of the protection pavilion at the current stage,as the quantitative study of environmental control design is still in its infancy,the site itself is still not properly protected.The reasons include: the archaeological sites are numerous in number,large in volume,immovable,and complicated in composition;there are many environmental mutations and fluctuations in the archaeological excavation process,and these factors have brought many difficulties to the research and design of environmental control and protection technologies.This article takes the Sun Wu tomb in Nanjing Shangfang as the main monitoring and research object,based on the material properties and deterioration mechanism of the material of the tomb,and combing and analyzing the protection and display facilities of archaeological sites.Based on the relevant design elements of the environment,a calculation model for fluctuations in temperature and humidity of the external air environment,fluctuations in the temperature and humidity inside the protection display facility,and hydrothermal migration of the site was established to quantify the protection of the archaeological sites in the protection pavilion under different environmental control strategies(structural materials,The form of protection,ventilation and lighting,etc.),and the requirements for the control of the preservation environment of suitable archaeological sites provide quantitative support for the optimal design of environmental control strategies for archaeological sites.This article first through literature research and field research to find out the relationship between archaeological sites and the dependence of the environment;followed by Nanjing Shangfang Sun Wu Tomb as a practical research case to clarify the relevance of the dependent environment of archaeological sites and disease characteristics,based on the case point establish a numerical simulation model of heat and moisture coupling to quantify the correlation between environmental and disease dependencies,and compare and evaluate the environmental impacts of different design elements(construction materials,different ventilation and lighting),and refine the environmental control strategy of the protection and display facilities of brick archaeological sites in China.The research on the protection and display facility of architectural sites,which is based on environmental control strategies,will help promote the scientific development of design for cultural heritage protection and exhibition project.It will help cross-fusion and enhancement of heritage protection,architectural technology,architectural design,and architectural history,and provide scientific basis and theoretical support for the preventive protection of architectural heritage.At present,there is little research on the simulation and analysis of the quantitative relation between the degree of deterioration of archaeological sites and the strategies of protection and display from the perspective of hydrothermal migration.This article makes active explorations in quantifying the effect of protection strategies of archaeological sites protection and display facilities,and provides scientific basis for the research and practice of protection and architectural design for architectural sites.
