摘要/Abstract

摘要： 土体受到酸性溶液污染，会引起成分、微观结构、力学指标的变化.本文通过质量分数为0(清水)，1%，4%，8%，12%盐酸的浸泡试验，模拟粉土受酸溶液污染.由室内固结快剪和快速固结试验，得到受侵蚀粉土抗剪及压缩指标的变化规律.结果表明:黏聚力增加，内摩擦角减小，压缩模量减小，压缩系数、压缩指数变大.通过矿物分析、电镜扫描，从土的组成成分、微观结构两方面对变化进行解释.土体抗剪和抗压缩能力的改变，势必引起承载力和边坡稳定等相关指标的变化.因此在勘察设计和某些事故的成因分析时，对有酸污染隐患的粉土地区应考虑上述变化的情况.

Abstract: The composition， microstructure and mechanical indexes of the soil can be changed by acid solution. Through the 0 (water)，1%，4%，8%，12% concentration of hydrochloric acid solution soak tests， the silt polluted by acid solution was simulated. The variability of resisting shear and compression index about the corroded silt was gained by indoor consolidated quick shear test and quick consolidation test. The results show that the cohesive force is increased， the internal friction angle and the compression modulus are decreased， and the compression coefficient and the compression index are increased. The reason for the corroded silt property variation about material composition and microstructure was explained by the results of the chemical composition analysis and scanning electron microscope. The relevant indexes of bearing capacity and slop stability will be changed consequentially because of the variations about resisting shear and compression ability. Therefore， the above variable conditions should be considered in the survey design and analysis of the accident causes for the silt region with acid pollution hazard.

Key words: contaminated soil, resisting shear and compression index, microstructure, mineral composition, mechanism of action
