摘要
文章以明长城的破坏情况为背景,通过对比研究各类型修复土壤在城墙修复中的作用,针对修复土壤的吸水性、抗压性、抗渗性、抗裂性进行分析,对比传统改性土、化学改性土、细菌诱导土的修复特性,试图找到能够最全面有效修复城墙的土壤类型。结果表明:传统改性土三七灰土、糯米灰膏改性土具有较为优良的综合实用性能。化学改性土在2.0%的甲基硅酸钠、5.0%的石灰、2.0%的胶粉时性能最优。细菌诱导土中浓度2.8×10^(8)CFU/mL的枯草芽孢杆菌、1×10^(5)CFU/mL的巨大芽孢杆菌和巴氏芽孢杆菌具有较为优良的综合实用性能。
Based on the destruction of the Great Wall in Ming Dynasty,this paper makes a comparative study on the role of various types of remediation soil in the restoration of the city wall,analyzes the water absorption,pressure resistance,impermeability and crack resistance of the remediation soil,and compares the restoration characteristics of traditional modified soil,chemically modified soil and bacteria-induced soil,trying to find the most comprehensive and effective soil type for the restoration of the city wall.The results show that the traditional modified soil-pseudo-ginseng lime soil and glutinous rice plaster modified soil have excellent comprehensive practical properties.The chemical modified soil has the best performance when it contains 2.0%sodium methylsilicate,5.0%lime and 2.0%rubber powder.The bacteria-induced soil with concentrations of 2.8×10^(8)CFU/mLBacillus subtilis and 1×10^(5)CFU/mL Bacillus megaterium and Bacillus pasteurella has excellent comprehensive practical properties.
