摘　　要：湿陷性土初始孔隙度高、饱和度低、粉砂含量高,受水浸湿后受应力变化极易发生沉降变形,沉降严重时将对地上建筑造成不可逆转的重大破坏,因此提高湿陷性土的物理力学性能受到越来越多的关注。本研究分别分析了纳米材料、纤维、聚合物、工业废弃物、微生物等加固材料处理湿陷性土的可行性和有效性,探讨了加固材料未来发展趋势,为加固湿陷性土壤等不良地层提供一定的参考。Collapsible soils have high initial porosity,low saturation and high chalk content,which are very prone to settlement and deformation by stress changes after being wetted by water,and will cause irreversible and significant damage to the above ground building when the settlement is serious.Therefore,improving the physical and mechanical properties of collapsible soils have received more and more attention.In this study,the feasibility and effectiveness of reinforcing materials such as nanomaterials,fiber,polymers,industrial waste and microorganisms in treating collapsible soils were respectively elaborated.The development trend of reinforcing materials was explored,so as to provide certain references for the reinforcement of poor strata such as collapsible soils.
