Quantitative assessment method for stone cultural relic component weathering and security degree

Abstract

A quantitative assessment method for stone cultural relic component weathering and security degree includes the following steps: selecting physical properties which can be achieved through lossless or micro-damaged detecting and capable of reflecting features of rock weathering and security as evaluation indexes according to protective principles of cultural relics, distributing corresponding weighted values to all the evaluation indexes through an expert scoring method to reflect degree of impact of different indexes to the component weathering and the security degree, dividing weathering degree into five levels and the security degree into four levels and formulating point values for all levels, preliminarily determining the weathering degree and the security degree according to a single evaluation index, and adopting a point weighting method to calculate final weathering points and security points of all the components to achieve the weathering degree and the security degree of the component visually and accurately.

Description

technical field [0001] The invention relates to the field of cultural relics protection, in particular to a method for evaluating the weathering level and safety level of stone cultural relic components in a quantitative manner. Background technique [0002] The weathering and safety status of stone cultural relics affect the integrity, appreciation and value of cultural relics, and there are hidden dangers of cultural relics and personal safety. The detection and evaluation of them can meet the requirements of heritage management departments and the public. Detection and evaluation The results can provide a reliable basis for subsequent protection work. The key to evaluating the weathering and safety of stone cultural relics is first to use non-destructive testing methods to detect stone cultural relics, and secondly to choose feasible, suitable and accurate evaluation indicators and evaluation methods. Due to the non-renewability of cultural relics, all activities carried...

AI Technical Summary

Problems solved by technology

Due to the non-renewability of cultural relics, all activities carried out on them cannot damage cultural relics, so the detection methods are limited to non-destructive or minimal damage methods; in addition, on the one hand, due to the different degrees of influence on the components themselves due to the type of component weathering and the corresponding physical properties , it is difficult to comprehensively evaluate the weathering and safety degree of the entire component from a single physical property index; The main method cannot accurately assess the degree of adjacent weathering
