摘要针对岩石介质中水分湿润锋的时间、空间演化规律问题，采用红外热像仪监测砾岩由干燥到饱和吸水过程中的红外辐射特征，利用水分湿润锋识别理论分析水分湿润锋在时间、空间上的分布规律：(1) 随着时间推进，不规则湿润锋面由试样底部逐渐运移至试样顶端，在吸附力与毛细力的主要作用下，其上升速度不断减小，直至趋近于0；(2) 受砾岩材质不均匀影响，在空间上，水分湿润锋面从试样底部到顶端呈现为非对称的上凸曲线的阵列。对比理论计算结果与可见光监测结果表明，利用水分湿润锋识别理论，能够得到任意时刻砾岩水分湿润锋面的空间分布曲线，可进一步追踪其在时间、空间上的演化规律；该方法可实现无损、实时追踪水分湿润锋的目的，对解决土木工程建设、古建筑维护、文物保护等领域的水害问题可提供一种新的监测方法。

Abstract：According to the law of time and space evolution of moisture wetting front in rock medium，Infrared radiation characteristics of conglomerate from dry to saturated water absorption were monitored by infrared thermography. The distribution of moisture wetting front in time and space is analyzed by the theory of moisture wetting front identification：(1) As time progresses，the irregular wetting front gradually moves from the bottom of the sample to the top of the sample. Under the main action of adsorption force and capillary force，the rising speed decreases continuously until it approaches zero. (2) Due to the unevenness of the conglomerate material，in space，the moisture wet front presents an array of asymmetric convex curves from the bottom to the top of the sample. By comparing the results of theoretical calculation and visible light monitoring，it is shown that the spatial distribution curve of water wetting front of conglomerate can be obtained by using the theory of water wetting front identification at any time，and the evolution law of water wetting front in time and space can be further traced. This method can realize the purpose of non-destructive and real time tracking of moisture wetting front，and can provide a new monitoring method to solve the problems of water damage in civil engineering construction，ancient architecture maintenance，cultural relic protection and other fields.
