The permeating experiments results indicate that permeability coefficient of clay-solidified grouting curtain is closely related to solid mass, the contribute of clay is higher than that of cement, its permeability of heavy metal cations decrease with leakage time for flowing passage are blocked up by precipitate in cations moving through clay-solidified grouting curtain, moving velocity are varied for different heavy metal cations in clay-solidified grouting curtain and the selectivity order is Hg2+> Pb2+ in the experimental circumstance. Furthermore, antisepsis capabilities of clay-solidified grouting curtain are demonstrated by contrast tests., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

articleAbstract=通过渗透实验研究了粘土固化注浆帷幕浆液配比对抗渗性能的影响,测试了其对重金属离子的抗渗性能,比较了不同重金属离子的迁移速度,并通过对比实验分析了其防腐性能。实验结果表明:粘土固化注浆帷幕的抗渗性能随着固相含量的增加而增强,且粘土对抗渗性能的贡献大于水泥;重金属离子在粘土固化注浆帷幕中迁移时可生成难溶的沉淀物,堵塞帷幕的导水通道,改善帷幕的孔隙结构和孔级配,使帷幕的抗渗性能随渗透历时逐渐增强;不同重金属离子在帷幕中的迁移速度不同,实验条件下的迁移速度Hg2+>Pb2+;实验验证了粘土固化注浆帷幕具有较好的防腐性能。,
