Conservation Research of the Farmland of the Sanyangzhuang Site of Han Dynasty

摘要

Sanyangzhuang Site of Han Dynasty which lies in Neihuang Xian,Henan Province was discovered in June 2003.This site was a settlement of Han Dynasty which was submerged as a whole due to the inundation of Yellow River,and kept the farm production and living scenes completely.Large areas of farmland were conserved in the site,which is of most importance.As experts considered,not only the construction relics but also the farmland,which is more important,should be protected.The earth samples from Sanyangzhuang Site were analyzed to provide information for the selection of the protective material and the mechanism of soil reinforcement was further explored.According to the characteristic of the project including quality of soil and the scope of application,alkoxy organosilicone monomer instead of ethyl silicate oligomer was selected as the protective material and suitable additions such as elastieizer were added to.By testing the unconfined compressive strength of the reinforced samples after water immersion of 24h,the most scientific and suitable batch formula and treating and operation technology were selected.
