东南沿海木构文物建筑病害诊断研究

Research on the Disease Diagnosis of Wooden Architecture Heritage in the Southeast Coast of China

以我国东南沿海地区木构文物建筑为例,使用LS-SVM和随机森林算法,建立该地区文物建筑病害与微观环境参数之间的数学模型。利用该模型对被试文物建筑进行盲检,从病发、病症、病情3个方面做出病害诊断,诊断结果与真实病害情况相匹配。该诊断方法以病害的微观环境参数为鉴定依据,将诊断过程简化为参数的运算过程,实现对文物建筑病害的准确判断,并对新修复的文物建筑未来可能发生的病害进行预警,旨在为文物建筑保护技术与理性决策提供新的科学支持。

In this paper,taking the wooden architecture heritage in the southeast coastal area of China as an example,using LS-SVM and the random forest algorithm,a mathematical model between the diseases of architecture heritage and micro-environmental parameters in this area is established.The model is used to blind check the architecture heritage under test,and make disease diagnosis from three aspects:disease occurrence,disease symptoms and disease condition,the diagnosis results match the real disease situation.The diagnosis method takes the micro-environmental parameters of the disease as the identification basis,simplifies the diagnosis process into the calculation parameters process,realizes the accurate judgment of the diseases of architecture heritage,and warns the possible diseases of the newly repaired architecture heritage in the future.The research aims to provide new scientific support for the protection technology and rational decision-making of architecture heritage.
