基于红外热像的传统砌体含水特征检测实验研究

摘要

该文基于红外热像技术,对两种砖砌体进行渗水实验,找出两砖表面温度一维分布与表面含水率一维分布之间的关系,分别确定了砖砌体渗水后最低温度区和含水率最高点的方法,得出体现砖砌体温度与含水率两者相互关系的回归方程,从而初步建立砌体建筑潮湿病害的定量分析方法,进而将红外热像技术应用于历史建筑的保护工作中.%Based on infrared thermal imaging technology for seepage test of two kinds of brick masonry, we find out the relationship between the distribution of one-dimensional two bricks surface temperature and one-dimensional surface moisture content, and determine the method of minimum temperature zone and the highest point of seepage after the brickwork. Then we obtain the regression equation which shows the relationship between the temperature and moisture content of brickwork. Finally we initially establish the quantitative analysis of damp diseases in masonry buildings, and apply the infrared thermal imaging technology to the protection of historic buildings.
