文化遗产受其周围环境条件的影响是多方面的。高松冢墓壁画的劣化原因之一是其表面潮湿的小气候。为了控制这些问题所造成的壁画劣化，从环境因素的多个方面进行研究是非常重要的，如温度、湿度、文物的含水量、干湿循环等。这些变量可能无法通过1-D或2-D完全预测，以确定壁画的劣化位置和程度。本文展示了如何开发的3-D湿热模型，以期分析的保存措施，允许量化的干燥和冷凝过程发生在地下室的表面上的程度。研究结果表明，为了保护地下室内的壁画，周围土丘与保护对象之间的温差应尽可能保持恒定。该方法适用于其他壁画保护措施的效果评估。
Abstract Cultural properties are variously influenced by their surrounding environmental conditions. One of the reasons for the deterioration of mural paintings in the Takamatsuzuka Tumulus was the humid microclimate on their surface. In order to control the deterioration of mural paintings caused by such problems, it is important to investigate the environmental factors from various aspects, such as the temperature, humidity, water content of cultural properties, wetting and drying cycles and so on. As for the research concerning hygrothermal behavior on mural paintings, these variables may not be thoroughly predicted by 1-D or 2-D for determination of the location and degree of the deterioration of mural paintings. This paper shows how a 3-D hygrothermal model developed with a view to analyzing the preservation measures that allow quantifying of the degree of drying and condensing processes occurred on the surfaces of the underground chamber. The findings show that for the purpose of preserving mural paintings within the underground chamber, the temperature difference between the surrounding mound and the protected object should be kept as constant as can be practically achieved. This method is applicable for estimating the effects of preservation measures for the conservation of other mural paintings.
