摘要
永佑寺避暑山庄后序碑驮碑赑屃西侧尾部存在较大开口裂隙,这可能对石碑的稳定性造成影响。由于赑屃形状不规则而且体积巨大,目前的检测技术很难直接检测出裂隙在赑屃内部的走向及深度。红外热像测试从温度分布的角度出发,借助24h内温度场的变化图像,对赑屃内部裂隙及水份进行分析,结果显示:该方法可以测出裂隙在内部的走向,为后续碑体的稳定打下基础。
A big crack could be seen on the tail of the Bixi,carrying the epilogue tablet of Chengde Mountain Resort epilogue.It would affect the stability of the stone tablet.Because of the irregular shape and huge size of the Bixi,it is difficult to measure the depth and trend of the crack on it by routine test methods.The effect of the crack and moisture on the Bixi could be analyzed by using infrared thermography based on the change of the temperature distribution in twenty four hours.
