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 […]
