晋阳古城遗址加固材料筛选及配比试验研究

Study on the Optimal Proportion of Consolidation Material for the Ancient City of Jinyang

对当前土遗址加固材料进行调研和分析基础上,提出了遗址土中加入石灰和水性丙烯酸酯乳液的加固材料方案;并对加固前后土体的强度特性、耐水性能、收缩特性等进行了试验研究。研究结果显示,石灰和水性聚氨酯/聚丙烯酸酯乳液混合加固材料对土遗址保护加固具有良好效果;并提出了加固材料的最优配比。

Based on the analysis of materials for conservation and consolidation in the field of earth sites, the scheme of adding lime and waterborne polyurethane/polyacrylate to the soil of earth sites is proposed. These characteristics related to mechanics, strength, water resistance, shrinkage were tested. The results show that the reinforced specimens following the scheme have the best comprehensive properties. The optimal proportions of lime and acrylic emulsion have also been determined.
