【摘要】：土遗址对于我国历史研究有着举足轻重的地位。当前我国土遗址类文物损害较为严重,仅第三次全国文物普查中就发现有23599多处上次文物普查登记的文物消失。因此,对它们的保护工作就显得尤为重要和迫切。目前,土遗址保护在病害综合评估模型构建方面存在两方面缺陷:一是土遗址病害发生概率及其影响因子作用效果定量计算不足;二是土遗址监测数据没有参与综合评估,影响了土遗址病害客观性评价。为此,基于模糊计算基本原理,本文提出了土遗址病害一级和多级模糊计算方法;通过研究分析土遗址病害与监测数据客观评价关系得到较为客观的土遗址病害发生概率值;从土遗址载体病害和本体病害出发,利用土遗址病害多级模糊计算方法反推得到较为准确的土遗址病害全部隶属度;最后采用该隶属度结合土遗址病害多级模糊计算方法构建了土遗址病害模糊计算综合评估模型,实现针对土遗址病害发生概率及其影响因子作用大小更为准确的定量计算。同时,基于Auto CAD Civil3D平台,采用C#语言和Visual studio 2012进行土遗址病害综合评估系统原型设计与开发,系统集成了土遗址病害模糊计算综合评估模型,实现土遗址监测特征数据提取、土遗址数据预处理和土遗址病害评估等功能,得到较为平滑的计算结果。实例分析表明,本模型达到了针对土遗址病害切实有效的综合评估目的,为制定土遗址保护方案提供了较为准确的依据。
[Abstract]:Earthen sites play an important role in the study of Chinese history. At present, more than 23599 cultural relics registered in the last cultural relic survey have been found to have disappeared in the third national cultural relic census. Therefore, the protection of their work is particularly important and urgent. At present, there are two defects in the construction of comprehensive disease assessment model in the protection of earthen sites: one is the lack of quantitative calculation of the probability of occurrence of the disease and the effect of its influence factors, the other is that the monitoring data of earthen sites do not participate in the comprehensive evaluation. The objective evaluation of earth site diseases is affected. Therefore, based on the basic principle of fuzzy calculation, this paper puts forward the first-order and multi-stage fuzzy calculation method of the earth site disease, and obtains the more objective probability value of the occurrence of the earth site disease by studying and analyzing the relationship between the earth site disease and the objective evaluation of the monitoring data. Based on the carrier disease and the body disease of the earth site, the more accurate degree of membership of the soil site disease is obtained by using the multistage fuzzy calculation method of the earth site disease. Finally, the fuzzy comprehensive evaluation model of the disease of earthen site is constructed by combining the multi-stage fuzzy calculation method of the disease of the earth site with the membership degree, which can realize the more accurate quantitative calculation for the probability of occurrence of the disease and the effect of the influencing factor on the occurrence probability of the disease. At the same time, based on the Auto CAD Civil 3D platform, the prototype design and development of the comprehensive evaluation system for earth-site diseases are carried out by using C # language and Visual studio 2012. The fuzzy comprehensive evaluation model of earth-site diseases is integrated into the system, and the feature data of earth-site monitoring are extracted. The functions of data preprocessing and disease evaluation of earthen sites are used to obtain a smooth calculation result. The analysis of examples shows that the model achieves the purpose of comprehensive evaluation for the disease of earthen sites, and provides a more accurate basis for formulating the scheme of protection of earthen sites.
