摘　　要：通过对秦俑二号坑土壤胀缩作科学研究,监测数据对比,运用土壤干缩特征理论,构建了秦俑二号坑土壤干缩特征曲线,结果发现秦俑二号坑干燥进程较为迅速,2000年以前二号坑干燥化尚未对彩绘陶器造成威胁和侵害,但近年来土壤含水量已由挖掘初期的15%～20%,降低到目前的2%～8%,对坑下文物表面彩绘构成威胁。通过补充土壤水份等办法可以减缓这种变化。This paper studies the soil in pit No 2 Qin Terracotta, comparison with the data collected, we got the soil shrinkage characteristic curves. The results show the soil drying process in pit No. 2 quicken its step clearly, at the beginning of the soil shrinkage process. There were not too much affection to the underground the polychrome pottery. Up to now, water content of soil in pit No. 2 Only 2 - 8%, it threaten greatly the polychrome relics of underground. And in the end, how to slow down the pace are discusse.
