用夯筑方法建造的土遗址在公开展示之前需要对土遗址的本体进行修复和加固。通常采用合成树脂作为土遗址本体和表面处理的材料，但合成树脂作为加固材料存在着一系列的问题，如会降低土体强度及对构造造成破坏。本工作针对日本九州地区广泛分布的真砂土和火山灰土为材料修筑的土遗址修复工程，尝试运用石灰、糯米汁、桐油作为土遗址的修复材料。按照不同的配合比制作试验土样进行无侧限抗压、固结、干湿循环、冻融循环等试验。结果显示，添加了4％桐油和石灰的土样能够大幅度提高夯土的强度，且压缩性低、抗冻融性好，尤其能显著提高土样的抗干湿劣化的性能。建议在九州地区的土遗址修复和保护工程中运用。

Before compacted soil ruins are open to the public, they need to be restored and reinforced. Usually, asynthetic resin （polyurethane resin） is used to reinforcement the ruin＇s body and surface. However, there are a series of problems when the synthetic resin is used, such as the decrease in the soil＇s strength and the damage to the ruin＇s structure. This paper shows an attempt of using slake lime, glutinous rice cooking soup and tung oils to reinforce ruins constructed of Masa and Volcanic soils which are widely distributed in Kyushu Japan. The unconfined compression, odeometer, drying and wetting durability and freezing and thawing durability tests were carried out on samples prepared with different patterns. Tests results show that addition of 4% tung oils and slake lime into the samples could dramatically increase the strength of compacted soils. Samples have good compressibility and freezing and thawing durability. In particular, the drying and wetting durability is reinforced. The method could be applied in resto- ration projects on fill ruins located in Kyushu area,Japan.
