Liquefaction-Induced Damage In The2010-2011 Christchurch (New Zealand) Earthquakes, Misko Cubrinovski Apr 2013

Liquefaction-Induced Damage In The2010-2011 Christchurch (New Zealand) Earthquakes, Misko Cubrinovski

International Conference on Case Histories in Geotechnical Engineering

A series of strong local earthquakes hit the city of Christchurch (New Zealand) in the period between September 2010 and December 2011. The earthquakes produced strong ground motions, and were very damaging. The magnitude 6.2 22 February 2011 earthquake was particularly devastating causing heavy damage to the city and 185 fatalities. The earthquake caused widespread and severe liquefaction over approximately one third of the city area which arguably was the most severe and extensive liquefaction in native soils on record. This paper presents an overview of the liquefaction-induced damage to the land, buildings and infrastructure caused by the 2010-2011 earthquakes.

Barrette Foundations — Two Case Histories From Turkey, H. Turan Durgunoglu Apr 2013

Barrette Foundations — Two Case Histories From Turkey, H. Turan Durgunoglu

International Conference on Case Histories in Geotechnical Engineering

In the recent decades construction of tower structures in big cities around the world is a new trend that has been followed. As a result, engineers are faced with foundations to be designed and constructed under heavier super structural loads imposed by such structures. Often, poor subsoil conditions, site heterogeneity, variability in geometry, and high seismicity brings further challenge in cost effective and safe foundation design. To overcome such complexities and meet higher load capacity requirements often barrette foundations have been utilized instead of cast in situ circular large diameter piles. In this paper applications of barrette foundations together with …

Performance Of Two Geosynthetics-Lined Landfills In The Northridge Earthquake, Edward Kavazanjian Jr., Mohamed Arab, Neven Matasovic

International Conference on Case Histories in Geotechnical Engineering

Analyses of the performance of the Chiquita Canyon and Lopez Canyon landfills in the 1994 Magnitude 6.7 Northridge earthquake illustrate deficiencies in the current state-of-practice for seismic design of geosynthetic liner systems and the promise of a new state-of-the-art method for performance-based design, and suggest necessary modifications to construction quality assurance procedures for geosynthetic liner systems. Analyses of the Chiquita Canyon landfill case history using the conventional state-of-practice Newmark Analysis approach fail to predict the tears observed at the landfill following the earthquake in the side slope liner geomembrane at two different locations. However, the state-of-the-art finite difference based method …

Probabilistic Geotechnical Analyses For Offshore Facilities, Suzanne Lacasse, Farrokh Nadim Apr 2013

Probabilistic Geotechnical Analyses For Offshore Facilities, Suzanne Lacasse, Farrokh Nadim

International Conference on Case Histories in Geotechnical Engineering

Society requires increasingly that the hazard and risk associated with engineered constructions be quantified. The paper presents ge-otechnical hazard assessment in the context of a risk framework. Concepts of uncertainties, reliability, safety and risk are briefly re-viewed. The use of the approach is exemplified for offshore facilities, including a piled foundation, a gravity foundation, a jack-up structure and underwater slopes. The applications demonstrate that probabilistic analyses complement the conventional deterministic safety factor and deformation-based analyses, and contribute to achieving a safer and optimum design. The conclusions emphasize the usefulness of a risk assessment, the importance of engineering judgment in the …

Foundation Failure Case Histories Reexamined Using Modern Geomechanics, Rodrigo Salgado, Andrei Lyamin, Jeehee Lim

International Conference on Case Histories in Geotechnical Engineering

Case histories have played an important role in guiding development of geotechnical engineering during a time when theory was not sophisticated enough to model even simple problems with an acceptable level of rigor. As the discipline transitions from overwhelming reliance on empiricism to a greater reliance on science, it is useful to reexamine the best known case histories as a general check on modern methods of analysis. In the engineering of foundations in clay, three case histories  the collapses of the Transcona and Fargo grain elevators and the near collapse of the leaning tower of Pisa  stand out. …

Phytoforensics: Soil And Groundwater Sampling Without Soil Or Groundwater!, Joel G. Burken, Kendra M. Waltermire

International Conference on Case Histories in Geotechnical Engineering

Plants directly interact with surrounding water, air, and soil, collecting and storing chemicals and elements from the surrounding environment. Tree coring methods have shown that groundwater contamination can be assessed without directly sampling the groundwater. In this work, two new and innovative sampling methods that place sampling devices inside the plant, i.e. “in-planta”, were developed to access this valuable data that can direct and perhaps replace traditional methods for contaminated-site investigations. Traditional site assessments may be limited due to time, site access, and expense, resulting in incomplete understanding of the contaminated plumes and inefficient remedial approaches. The new techniques presented …
