文物劣化定量分析与评价软件系统

Quantitative analysis of the damage of monument and relevant evaluation software

目前,我国文物行业病害分析通常是定性描述,从而导致病害分析对比性差、档案价值差。为了实现对文物劣化的定量分析和系统评价,对AutoCAD进行了二次开发,建立了文物劣化定量分析与评价软件系统。通过对软件系统开发思路和特点的介绍,证实了用AutoCAD软件解决实际问题中的专业化和本地化的可能性和必要性。

The correct evaluation of monument status, including the size of damage area, the damage factors and trend, is the basis of determining the analytical techniques for studying the monuments.. Nowadays, damage analysis of monuments is usually qualitative in China, and the damage is classified into weathering, water action, collapse and human activities by cause, or into relief, discoloration and granular disintegration by appearance. The damage has been analyzed for many years, but it is difficult to compare the results because of their descriptive evaluation. To evaluate quantitatively and compare these results, quantitative analysis and relevant evaluation software were developed by using VBA in AutoCAD. The application defines 25 kinds of monument damage and figures the corresponding patterns. Hatching pattern can be easily accomplished by clicking mouse. Different damage factor is given to each kind of which means the damage damage , and the whole monument can be classified according to the Damage Index （DI） intensity. Besides, the damage area and its factor can be calculated. , The classification can be illustrated using AutoCAD. Conversion between AutoCAD and Excel data is built, so it is convenient to analyze the data. It is proved that it is necessary and possible to develop software for quantitative analysis of the damage of monument.
