Abstract

As precious cultural heritage, earthen sites are susceptible to various natural factors, leading to diverse forms of degradation. To protect earthen sites, the effects of super absorbent polymers (SAPs) on soil water retention, physical properties, and color compatibility at different concentrations were studied. After applying SAP treatment to an earthen site with different degrees of weathering, we drew the following conclusions. SAP-2 improved soil water retention capacity, increased soil water content, and slowed down the precipitation of soluble salts. At the same time, SAP-2 had the least effect on soil color difference and reduced the development of cracks by filling soil pores and enhancing the cohesion between soil particles, thus giving the earthen sites better weathering resistance. Therefore, the results provide a useful reference for the surface cracking of earthen sites in semi-arid areas and the degradation caused by flaking and block spalling.

摘要

作为珍贵的文化遗产，土遗址易受各种自然因素影响，导致出现多种形式的退化。为保护土遗址，研究了不同浓度的高吸水性聚合物（SAPs）对土壤保水性、物理性质和颜色兼容性的影响。在用不同风化程度的土遗址进行SAP处理后，我们得出以下结论。SAP - 2提高了土壤保水能力，增加了土壤含水量，并减缓了可溶性盐的沉淀。同时，SAP - 2对土壤色差的影响最小，通过填充土壤孔隙和增强土壤颗粒间的凝聚力减少了裂缝的发展，从而使土遗址具有更好的抗风化能力。因此，研究结果为半干旱地区土遗址的表面开裂以及片状剥落和块状剥落引起的退化提供了有益参考。
