甘肃河西地区馆藏画像砖物理力学性质试验

On the Physico-mechanical Properties of the Painted Bricks in Museums in the Hexi Region of Gansu Province

本文对甘肃河西地区敦煌、酒泉、嘉峪关、高台博物馆部分馆藏画像砖物理力学性质进行了分析研究。结果表明,画像砖易溶盐含量很高;画像砖的孔隙发育程度、孔隙分布情况、颜色都有差异;砖体均匀性差,强度差异大;但有些画像砖虽经十几个世纪的存放,其平均力学强度仍然很高。画像砖的物理性质分析还反映出了古代制砖的工艺及水平,为今后开展画像砖病害修复提供了有针对性的基础研究资料。

This paper presents a study on the physical-mechanical properties of the painted bricks collected in the museums ofJiuquan, Dunhuang, Jiayuguan and Gaotai in Hexi Regions of Gansu Province. The results show that the content of soluble salts in these painted bricks is high, and they differ in the porosity, pore distribution, color, uniformity and intensity. However, more than ten centuries later, some of them still remain a high average mechanical intensity. The results also reflect ancient brick-making technology and level, and provide basic information for future conservation.
