摘　　要：随着我国对于城市发展定位与发展规划的重新调整,工厂的迁离遗留了大量的重金属污染场地。国家近年相关政策动作不断,显示了对于土壤污染的重视和防治土壤污染的决心。污染土的修复改良处理是一种积极主动的处理方法,在土壤修复改良技术中固化/稳定法既可提高土体强度,又可降低重金属离子的溶出,是重金属污染场地修复处理技术中应用最广泛的方法之一。固化/稳定化材料种类繁多,并通过不同的固化机理作用于污染土体。本文归纳了以往学者的相关研究进展,论述了固化污染土的无侧限抗压强度和重金属浸出浓度的影响因素并介绍了国内外大型污染场地修复案例。With the readjustment of urban development orientation and development planning, the relocation of factories has left behind a lot of heavy metal contaminated sites. The state＇s policy actions in recent years show the importance of soil pollution and the determination to prevent soil pollution. Remediation of contaminated soil is a kind of active treatment method.The solidification/stabilization technique can not only improve the strength of soil, but also reduce the dissolution of heavy metal contaminated ions, which is one of the most widely used methods in remediation treatment of heavy metal contaminated sites. There are many kinds of solidified/stabilized materials, which are used to pollute soil by different curing mechanism. This paper sums up the relevant research progress of the former scholars and discusses the factors influencing the unconfined compressive strength and the leaching concentration of heavy metals in the solidified contaminated soil and introduces the cases of large-scale contaminated site restoration at home and abroad.
