The Study Of Evaluating The Immobile Cultural Relics’ Degradation Situation

Unmovable cultural relics are exposed to the natural environment for a long time,because a variety of natural factors and man-made destruction,the material performance degradation,deterioration occurs in a large number of unmovable cultural relics.There will be more and more relics disappear.In order to identify and protect the fragile relics in time,the scientific examination and evaluation of the degree of deterioration of non-removable cultural relics are needed.In recent decades,due to the continuous progress of scientific and technological testing in various fields,and the increasing demand of cultural relics in the field of heritage preservation,the nondestructive testing technology is increasingly widely used in the detection of the degree of deterioration of cultural relics,and many accomplishments have been achieved.The current situation of application is mainly use single-class instrument to detect and contrast the material and the same kind of fresh materials to obtain the degree of material deterioration,such methods is highly refined t,and also achieved a lot of results.However,this kind of method must rely on the Scientific Research Unit laboratory to be able to carry on.There are a great number of Unmovable cultural relics in China so the need of detection of non-removable cultural relics is at a very high level,the existing research units are unable to meet the needs,so it is necessary to try to develop suitable for on-site use of the unmovable cultural heritage evaluation method.The paper aims to study the degree of material degradation of the non-removable cultural relics of masonry and mural by using a variety of portable nondestructive testing techniques.Through the investigation of the disease of stone relics of Yangxing House,golden bricks of Yanxi House and the physical properties of various materials analysis,the level of degradation and main degradation factors of the two kinds of cultural relics were obtained.In the case of the very scarcity of mural detection means,by investigating the incidence rate of all kinds of disease in murals of King Shi Palace,calculate different diseases and different degrees of disease,and the mural deterioration index was obtained.
