【摘要】 潮湿地区土遗址的加固是一个世界性的难题,为此,北京大学文博学院土遗址加固专家周双林教授研发了一种非水分散体的加固材料。但目前此加固剂的有效性还处于探索阶段,且其主要的试验研究多数限于中国西北地区,对中国西南潮湿地区土遗址的加固效果研究尚未发现有报道。为检验此加固剂对中国西南潮湿地区土遗址的加固效果,采用此加固剂对四川省成都市郊的邛窑遗址土样进行加固,研究了其颜色、重量、抗压强度、渗透速度、短期耐水性的变化,并与西北地区土遗址的相应试验进行对比研究。研究结果表明,周双林教授所研发的非水分散体土遗址加固材料对西南潮湿地区土遗址也有一定的加固和防水效果。更多还原

【Abstract】 It is a worldwide difficulty to preserve earth monument in wet area. To solve this problem,professor ZHOU Shuanglin,an expert of earth monument preserving with College of Archaeology and Museum,Peking University,developed a consolidation agent named acrylic non-aqueous dispersion. But the study on this consolidation agent is still in its initial stage at present for most of its experimental researches are limited to northwest china and no research reports aimed at wet area in southwest China were found so far.To check out the efficiency of this consolidation agent in wet area,southwest China,a consolidating experiment was conducted by applying this consolidation agent to soil samples from Qiongyao earth monument located in outskirt of Chengdu city,the capital of Sichuan province. In this experiment,the changes of color,weight,compressive strength,seeping speed,and short-term water resistance of specimens after consolidating were investigated and compared with those for northwest area. The study shows that acrylic non-aqueous dispersion consolidation agent developed by professor ZHOU Shuanglin is also effective to a certain degree for the earth monument in wet area,southwest China.更多还原
