| Abstract | 莫高窟是世界文化遺產地和全國重點文物保護單位,日益增加的由游客產生的固體廢棄物給莫高窟及我國其他世界文化遺產地保護提出了新課題。2007年選取莫高窟景區典型垃圾桶,對廢棄物進行實地抽樣調查,了解莫高窟旅游廢物數量和物理組分現狀。根據莫高窟環保部門10年間垃圾清運數量,統計并得出莫高窟旅游固體廢物與游客人數的相關關系,建立固體廢物發展趨勢預測模型。莫高窟氣候干燥,降水量稀少,蒸發強烈,適于建造基于蒸發蒸騰蓋層的準好氧衛生填埋場。從蒸發蒸騰蓋層原理出發,論文提出了毛細屏障蓋層的設計建議。通過室內擊實試驗,確定了莫高窟澄板土(粉土)的最大干密度為1.885g/cm3,最優含水率為12.2%;通過室內非飽和導水率試驗結果 ,擬合出了澄板土含水率及非飽和導水率與吸力水頭的關系,試驗研究成果可供處理莫高窟固體廢物的衛生填埋場底部襯里設計參考。
The waste produced by the increasing number of visitors at the Mogao Grottoes has become a new problem for the maintenance of this World Cultural Heritage site. Fortunately, the garbage cans in the tourist areas were selected in 2007 precisely to measure waste composition for the purpose of designing more efficient sanitary systems. Based on the waste collection data of the past 10 years from the Dunhuang Academy, a prediction model has been found predicting future waste levels with respect to visitor number. The area of this site is suitable for a semi-aerobic landfill with evapotranspiration( ET) cover due to rare rainfall and very strong evaporation. Based on the principle of ET cover, a primary design plan for a capillary cover has been proposed as well. Compaction tests indicate that the local Dengban soil(a kind of silted soil) has a maximum dry density of 1.885 g/cm~3 and anoptimum water content of 12.2%. In addition, unsaturated permeability tests havebeen conducted to establish a correlation between water content and unsaturated permeability withinthe suctionwater conservancy head. These research results are useful for designing the base of the proposed sanitary landfill at the Mogao Grottoes. |
