Description
Dynamic replacement was chosen as a preferred method of ground improvement for the purpose of providing adequate foundation for construction of coal loading infrastructure on a site underlain by soft estuarine sediment, at Newcastle, Australia. Dynamic replacement is an extension of dynamic compaction used in cohesive soils, whereby suitable granular fill is driven and compacted using high energy pounders to form large diameter columns. Cone penetrometer testing (CPT) was initially engaged to characterise the site for column design and then utilised as a gauge to assess the improvements achieved during initial site calibration trails. Finally, along with the flat plate dilatometer (DMT) the CPT was used as a quality assurance tool during the construction phase. This paper presents an assessment of the capability and reliability of the CPT for assessment of ground improvement and provides comparison with measurements obtained using the DMT.
