Observed Field Behaviour of Soft Clay due to Embankment Loading: A Case Study in Queensland, Australia
MetadataShow full item record
In this paper, the field behaviours of a trial embankment in Southeast Queensland are presented. The trial embankment is approximately 90m in length and 36m in width. It has two sections with vertical drains installed at a spacing of 1 m (Section A) and 2 m (Section C) triangular pattern, and a third section (Section B) without drains (control section). This trial embankment was constructed to observe the ground response upon loading, and evaluate the effectiveness of ground improvement techniques using vertical drains on the soft clays in this region. This paper presents the findings obtained from the field observations during construction. Deformation behaviour and pore pressure response below the instrumented embankment are investigated and the performance of vertical drains is discussed. This paper gives a classic case study of a trial embankment built on soft clay in Southeast Queensland, Australia.
