Abstract

Ground improvement techniques are now widely used in expressway and motorway projects in the coastal plain of Queensland where there are highly compressible and very low shear strength alluvial (and perhaps marine) deposits of very soft clays. These Holocene deposits often have high organic content, which at times is mixed with peat, and have high secondary consolidation and creep characteristics. This paper examines suitable improvement techniques, especially with chemical additives. The strength and compressibility characteristics of treated and untreated samples of soft clay are studied in the oedometer tests, unconfined compression tests, and triaxial tests. Of the additives such as fly ash, lime and cement used in this study, the 10 percent cement additive gave the best improvement in terms of increase in strength and reduction in compressibility. This paper examined and illustrated the effects of additives on soft clay. (Author/publisher) For the covering entry of this conference, please see ITRD abstract no. E208431.
