夯土建筑遗址表面温度变化特征及预报模型
Characteristics and prediction model of surface temperature for rammed earthen architecture ruins
摘要
Abstract
Infrared imaging system is used for earthen architecture protection in Ruins of Jiaohe for the first time, solving the problem of earthen architecture temperature measurement.The law of surface temperature changing with time and space for the wall of rammed earth architecture is obtained by field monitoring.It's come to a conclusion that solar radiation orientation of wall and the degree of wall surface weathering are significant factors which have an influence on surface temperature of earthen architecture.The maximum daily temperature difference of the wall reaches 35℃ during the monitoring.It can be supposed that the temperature difference will higher at extremes of heat and cold.The acute change of surface temperature weakens soil strength and exacerbates soil mass deterioration.The prediction model of the surface temperature for rammed earthen architecture, by which the daily temperature difference can be calculated, is established on the basis of above analysis, which provides data support to the researches on migration of hydrothermal and salt.关键词
