【摘要】 敦煌莫高窟壁画受到水盐运移影响而产生酥碱、空鼓等病害。为探究这些病害根源,本文首次在莫高窟开挖探井并取样,采用烘干法测试莫高窟崖顶以下20m内地层的含水量。测试结果表明:莫高窟崖体砂砾中平均含水量为1.6%,砂砾中水分分布较均匀。崖体中局部夹有粉质粘土和粉细砂透镜体,粉质粘土层含水量高达24%,粉细砂中含水量为3.6%。崖体砂砾中水分分布的首次确定将为研究壁画病害和莫高窟保护提供重要依据。更多还原

【Abstract】 Efflorescent and detachment destroy of the wall-paintings of the Mogao Grottoes in Dunhuang are due to water-salt transfer.This is the first time to test moisture content by drying,take samples at a exploratory well of 20 meters below the Mogao Grottoes cliff top.The test results show that the average moisture content of the conglomerate is 1.6% and the distribution is relatively equable.There are silty clay and fine-sand layers in the cliff rocks.The moisture content is 24% in the silty layer and 3.6% in finesand layer.The presentation of moisture distribution provides a basis for studying the wall paintings pathologies and conservation of the Mogao Grottoes.更多还原
