聚苯乙烯泡沫塑料轻质填土(SLS)的特性

The properties of stabilized light soil (SLS) with expanded polystyrene

为了寻求“不进行地基处理的软基处理方法”，通过减轻路堤填土重量来提高软基的稳定性和减少沉降。研究了聚苯乙烯泡沫塑料轻质填土SLS的轻质、高强、变形间的相关关系，找出有工程应用前景的配方。通过和常规路堤填土的比较，对SLS的工程性质进行了评价。特别从环保角度出发，探讨了利用废泡沫塑料碎粒的可能性。

 This paper deals with a method of raising the stability and reducing the settlement for soft foundation under an embankment． A way was sought for reducing the weight of the fill for embankment instead of treating soft soil in the foundation． For this purpose a new material named stabilized light soil SLS with expanded polystyrene having the properties of lighter weight and higher compressive resistance was studied and the relationships between the deformation of foundation and the weight as well as the resistance of SLS were obtained． Then the optimum prescription of SLS having the prospect of engineering application was found． Comparing with the case of normal fill material the behavior of SLS was appraised． Finally the possibility of using waste expanded polystyrene having the prospect of engineering application is also explored．
