Ground improvement for rail, port and road, infrastructure - from theory to practice

Conference Paper


Abstract


  • The transportation infrastructure in coastal regions of Australia has

    been expanded in recent years due to high population density and increased traffic

    volumes. Such expansions require the application of ground improvement techniques

    to improve performance and sustainability of the infrastructure. In this paper,

    innovative ground improvement techniques applicable to railway embankments, port

    reclamation and embankment fills are discussed. For ballasted rail tracks, the

    performance of different types of geosynthetics for improving the stability and

    drainage of railway tracks under high cyclic loading is investigated. Instrumented

    tracks were conducted to measure the in-situ stresses and deformations of ballast at

    Bulli, New South Wales (NSW), Australia. Furthermore, stabilization of soft

    formation soils underneath rail tracks using prefabricated vertical drains (PVDs) is

    also studied through finite element analyses and field measurements at Sandgate. The

    innovative use of the mixtures of coal wash (CW) and steel furnace slag (SFS) as the

    reclamation fill is demonstrated through laboratory and field investigations at the

    Outer Harbor extension of Port Kembla in Wollongong, NSW. The optimum CW-SFS

    mixtures that may meet most of the geotechnical specifications are proposed to be

    used as an effective structural fill. Finally, the design of the combined vacuum and

    surcharge fill system and the construction of the road embankment are described using

    a case study from the Pacific Highway upgrade project. Field data are presented and

    interpreted to demonstrate how the embankments performed during construction in

    both vacuum and non-vacuum areas.
