Vacuum Consolidation – Design and Case Studies
Within the framework of the International Webinar – Ground Improvement Techniques for Highway Constructions held on May 29-30, 2020, Jérôme Racinais has given a presentation titled:
Past, Present & Future of Ground Improvement in the Americas
This Keynote gives relevant information on the history, the current practices and the vision for future of Ground Improvement works.
40 Years of Roller Integrated Continuous Compaction Control (CCC) Anniversary Symposium & Exhibition
In 1978 the first CCC system was patented. Since then 40 years have passed, in which not only CCC has been established in geotechnical engineering worldwide, but has also significantly influenced the development of the rollers to high tech devices. The proceedings of the Anniversary Symposium “40 Years of Roller Integrated Continuous Compaction Control (CCC)”, held on November 29, 2018 in Vienna, Austria, can be downloaded hereunder:
Within the framework of the 19th ICSMGE held in Seoul in 2017, Prof. Buddhima Indraratna has presented the 4th Louis Ménard Lecture:
This 4th Louis Menard lecture presents an overview of the theoretical and practical developments of soft ground improvement via prefabricated vertical drains, PVD (including natural fibre drains) and vacuum preloading, with application to selected case studies in Australia.
In recent years, the Deep Mixing has increasingly been applied for the construction of earth and water retaining structures.
From practice, it has been experienced that there was a real need to develop execution and design rules adapted to the function of the soil mix wall (earth-water retaining, bearing, cut-off or a combination) including the temporary or permanent character of the application. This is the reason why the BBRI and the SBRCURnet publish the Handbook Soil mix walls – Design & Execution.
Written by an international group of experts, this book provides over 700 pages of case-histories collected from all over the world. Each case-history provides an overview of the specific technology followed by applications, and in some cases, comprehensive back analysis through numerical modelling is discussed. The book includes methods for employing bacterial and biological treatment, and native vegetation for stabilizing problematic soils. Specific case-histories included in the book concern: chemical admixtures, grouting, deep mixing, electrokinetic, thermal and explosion-based techniques and finally, bioengineering.
Written by a group of international contributors, Ground Improvement Case Histories: Embankments with Special Reference to Soil Consolidation and Other Physical Methods, employs the use of case-histories to illustrate and apply equations, numerical methods and technology to undertake even the most complicated ground improvement projects. In this book, each case-history provides an overview of the specific technology followed by field applications and in some cases comprehensive back-analysis through numerical modelling. Specific embankment case-histories with special reference to soil consolidation included are: Ballina Bypass (Australia), Tianjin Port (China), Second Bangkok International Airport (Thailand), Changi East reclamation (Singapore), Maizuru-Wakasa Expressway (Japan) and Colombo Airport Expressway, Sri Lanka. Other physical methods include performance of stone columns at Penny’s Bay reclamation in Hong Kong and PCC piles for highway and high-speed railway construction in China, among others.
Written by an international group of contributors, Ground Improvement Case Histories: Compaction, Grouting and Geosynthetics provides over 700 pages of international case-histories. Each case-history provides an overview of the specific technology followed by applications, with some cases offering a comprehensive back-analysis through numerical modelling. Specific case-histories include: The Use of Alternative and Improved Construction Materials and Geosynthetics in Pavements, Case Histories of Embankments on Soft Soils and Stabilisation with Geosynthetics, Ground Improvement with Geotextile Reinforcements, Use of Geosynthetics to aid Construction over Soft Soils and Soil Improvement and Foundation Systems with Encased Columns and Reinforced Bearing Layers.
