摘　　要：文章对原状土、重塑土和改性粉土的压实性、渗透性等主要防渗垫层指标进行了对比评价,结果表明,原状土和压实重塑土的渗透性不能达到1×10-7cm/s,而改性土具有较好的压实性和低渗透性;提出了该种粉质黏土垫层改性后的最佳掺灰比。A series of experiments on undisturbed and disturbed samples and the silt improved with lime from the north of Anhui Province are performed to evaluate several main indexes including compactibility and permeability. The results show that the silt improved with lime has higher compactibility and lower permeability than undisturbed and disturbed samples, and moreover its permeability can be in the order of 1×10^-7 cm/s when it is compacted under the optimum or near to the optimum water content. Based on the above experiments, optimal lime content of 12% is put forward. The results provide a basis and reference for similar projects.
