A Case Study of a Site Underlain by Collapsing Soils
West Kimberley Regional Prison, Australia Abstract Douglas Partners Pty Ltd, geotechnical and environmental consultant, undertook a geotechnical investigation for the proposed West Kimberley Regional Prison located in Derby, Western Australia, in 2008 and 2009. The site is underlain by Pindan Sand, a red-brown aeolian clayey sand that exhibits collapse potential. The aim of this paper […]
Verification of a deep soil-bentonite barrier wall using the CPTu
Bulla Road Bridge North Abutment Geotechnical Design and Construction Performance of Abutment Modification M. P. Chan, BEng/BA MIEAust and M.Y. Broise BSc (Hons) 26th November 2018 Abstract The remediation of a former steelworks site in Newcastle, Australia included the construction of the deepest open-trench groundwater barrier wall in the world (at the time of construction). Piezocone tests […]
The Design and Performance of Stone Columns at Kooragang Coal Terminal
Abstract This paper describes the application of vibro-replacement stone columns to improve a weak foundation and allow substantial savings in both the project schedule and the quantity of fill material. Recent expansion of the Kooragang Coal Terminal boosted the coal exporting capacity of the Port of Newcastle to 100 million tonnes per year. Port Waratah […]
Design and Construction of a Deep Soil-Bentonite Groundwater Barrier Wall in Newcastle
Abstract This paper presents geotechnical and geo-environmental aspects of the design and construction of one of the world’s deepest soil bentonite (SB) groundwater barrier wall at the former Steelworks site at Newcastle, Australia. The site is undergoing a $110 million remediation programme, and a critical part of the remediation strategy is the construction of a […]
Recent Application of Ground Improvement Technology in the Pacific Region – Part 2 of 2
Abstract Three main types of ground improvement technologies (Type I – consolidation assisted by drainage including the use of stone columns, Type II – Improvement by compaction, and Type III – Grout based vertical columns) and their range of applicability were introduced in Part 1 of this paper. This paper (Part 2) is intended to provide […]
Recent Application of Ground Improvement Technology in the Pacific Region – Part 1 of 2
Abstract Australia and the Pacific Region have recently experienced an unprecedented growth in diversity and application of soil improvement technologies, and enable construction on soft or unstable grounds. In addition to conventional preloading, stone columns, vibroflotation, and piled embankments, recently introduced ground improvement technologies now available in Australia and the Pacific Region include jet grouting, […]
Performance of an Instrumented Stone Column Load Trial at Kooragang Island, Newcastle
Abstract This paper describes a large scale load trial of a weak foundation treated with vibro-replacement stone columns, at Newcastle Australia. The trial represented a rare test of the performance of stone columns under significant load, and was closely monitored using an array of geotechnical instrumentation. The Kooragang Coal Terminal site is underlain by soft […]
Engineering Properties of Alluvial Soils
The modern cone penetration test provides a rapid and reliable method of profiling soil conditions, and is particularly suited to alluvial sediments such as encountered in many parts of the Newcastle area. Numerous empirical and theoretical methods have been developed to relate measured cone parameters to various engineering properties. This paper presents the results of […]
