本次试验是内蒙古文化厅文物处、内蒙古博物馆有关技术人员在大窑四道沟遗址地层剖面首次实质性的保护加固试验研究,是我区土遗址保护的探索性工作。选用的材料是经国家文物局推荐的由甘肃省敦煌研究院研制的“PS”材料,曾用于甘肃、新疆等地国家级遗址的保护,并取得了较好的效果。本次试验对大窑遗址四道沟地层剖面上部马兰黄土地层的保护加固取得了满意的效果。但是对离石黄土下部的加固保护没有取得预期的效果。离石黄土下部地层我们将在2002年度进行新的试验。本报告是2000年室内试验和2001年室外遗址试验工作的总结,对于离石黄土试验的最终结论我 This experiment is the first time that the relevant technical personnel of Inner Mongolia Museum, in the Department of Cultural Relics, Inner Mongolia Department of Cultural Affairs and Office of Cultural Affairs, carried out substantial protective and reinforcement experimental research on the stratigraphic profile of the Ssagougou site in Dayiyao. The selected materials are “PS” materials developed by Dunhuang Research Institute of Gansu Province, recommended by State Administration of Cultural Heritage. They were used for the protection of national sites in Gansu, Xinjiang and other places and achieved good results. The test has obtained satisfactory results for the protection and consolidation of the Malan loess strata in the upper part of the Silougou formation in the site of the Daoyao Site. However, the reinforcement protection of the lower part of Lishi Loess did not achieve the expected results. Lishi loess below the strata we will conduct a new test in 2002. This report is a summary of indoor tests in 2000 and outdoor sites in 2001. For the final conclusion of the test of Lishi loess
