土建筑遗址墙体温度变化规律

Monitoring the temperature changes of earthen architecture walls

热劣化在土遗址老化过程中起着不可忽略的作用.在新疆交河土遗址中,采用人工夯土墙植入硅半导体传感器的方式,进行温度监测.结果表明在墙体内部靠近西表面处的温度变化比其他墙体内部测点的温度变化更为剧烈。且从墙体表面向墙体中心有明显的温度梯度变化,可以得出环境温度变化影响着土粒的膨胀和收缩变形存在着差异性.

Thermal deterioration plays an important role in aging of ancient earthen architecture.Semi- conductor Si sensors were used to monitor the temperature changes in an artificially rammed earthen wall at Jiaohe Relics in Xinjiang,China.Test data show that temperatures at interior points near west wall surface changed greatly than that at other sides due to longer exposure to sunlight.An obvious tempera- ture gradient was observed from the surfaces to the inner core of wall,indicating a potential of differentia...
