【摘要】：在城市建设发展中,对既有或新建建筑进行安全检测非常必要。建筑缺陷如建筑渗漏、建筑外墙饰面砖空鼓、混凝土火灾损伤、灾损建筑问题等,传统的检测方法效率低、投资大且有一定危险性,寻找一种新方法能够高效率、安全、快速、准确的对建筑物进行检测成为了全世界建筑行业亟待解决的重大课题。红外热像技术的出现使得上述问题的解决成为了可能,它也以自己独特的优势,越来越被人们所重视。但是由于建筑结构非常的复杂,且它的组成材料具有各向异性,这就使红外热像技术在建筑领域的应用受到了限制。目前,我国的红外热像检测在建筑领域处于探索阶段,没有明确的检测标准,不利于红外热像技术的推广。在已有的检测缺陷的理论的基础上,通过理论研究,实际检测与分析,进行了下边几个方面的研究工作： (1)通过与传统建筑检测方法的对比,凸显了红外热像技术的优越性,并总结了套完整系统的红外热像技术检测的方案。 (2)对建筑物进行了实地的检测与分析,特别地首次将红外热像技术运用到了灾损建筑,即煤矿沉陷引起的建筑损伤的检测中,并运用软件对红外热像图进行分析处理, (3)通过调查问卷,初步建立了以模糊数学为基础的建筑综合评价方法；并采用了有限元分析软件ANASYS对影响红外检测的因素进行了分析。最后提出了几点需要亟待研究的问题。
[Abstract]:In the development of urban construction, it is necessary to check the safety of existing or newly built buildings. Building defects such as building leakage, building exterior wall decoration brick hollow drum, concrete fire damage, damage building problems, etc., the traditional detection method is low efficiency, large investment and dangerous. Looking for a new method can be high efficiency, safety and speed. Accurate detection of buildings has become a major issue to be solved urgently in the construction industry all over the world. The emergence of infrared thermal imaging technology makes it possible to solve the above problems, and it has been paid more and more attention with its own unique advantages. However, due to the complexity of the building structure and the anisotropy of its constituent materials, the application of infrared thermal imaging technology in the field of architecture is limited. At present, the infrared thermal image detection in our country is in the stage of exploration in the field of architecture, and there is no clear detection standard, which is not conducive to the popularization of infrared thermal imaging technology. On the basis of the existing theory of defect detection, through theoretical research, practical detection and analysis, the following several aspects of research work are carried out: 1) the superiority of infrared thermal image technology is highlighted by comparing with the traditional building detection method, and the scheme of infrared thermal image detection with complete system is summarized. In particular, the infrared thermal image technology has been applied to the damage detection of damaged buildings for the first time, that is, the building damage caused by coal mine subsidence, and the infrared thermal image map has been analyzed and processed by software. 3) based on the questionnaire, the comprehensive evaluation method of building based on fuzzy mathematics is established, and the factors influencing the infrared detection are analyzed by using the finite element analysis software ANASYS. Finally, some problems that need to be studied are put forward.
