A family of constitutive models for mine cemented backfill is presented. Four formulas for the density- and pressure-dependency of elastic moduli, five formulas for the density and pressure-dependency of friction angle and four formulas for the age-dependency of the elastic moduli and effective Read more... about A family of constitutive models implemented in PLAXIS to simulate cemented mine backfill

This paper presents a summary of the current construction procedures for urban excavations in Buenos Aires, Argentina. The geotechnical conditions are briefly described, and a few case histories are reported. These case histories include large excavations supported with posttensioned anchors, Read more... about Recent experiences with ground retaining systems in Buenos Aires, Argentina

After recent failures related to tailings storage facilities, the assessment of static liquefaction has become a major subject of interest in the mining industry. The standard procedures to evaluate global stability under liquefied conditions combines limit equilibrium with trigger analyses, Read more... about A comparison of procedures for determining the state parameter of silt-like tailings

Los túneles convencionales excavados en suelos son un ejemplo típico de proceso industrial en ingeniería civil, y también un problema típico de interacción terreno-estructura. Las técnicas de construcción de túneles de frente abierto se optimizan para que permitan el empleo de grandes equipos de Read more... about Validación de Procedimientos Constructivos para Túneles mediante Métodos Numéricos

In the last twenty years, sixteen pile-supported metro stations have been built in Buenos Aires in a wide range of geotechnical conditions. After an initial design of the construction procedures including partial open-trench (in two cases), all subsequent fourteen stations were excavated Read more... about Subway Stations Retaining Walls: Case Histories in Soft and Hard Soils

La terminal de contenedores Tecplata está ubicada en un predio de 42ha en la entrada del Puerto de La Plata, en la Provincia de Buenos Aires. La construcción se ejecutó entre los años 2008 y 2014, y requirió una inversión de más de 415 millones de dólares. Las obras de infraestructura de la Read more... about Aspectos geotécnicos de la ejecución del muelle Tecplata

La Central Termoeléctrica Ensenada Barragán está ubicada en el partido de Ensenada, La Plata, Buenos Aires. El perfil geotécnico característico de la zona registra un estrato superior de suelos arcillosos de mediana y alta plasticidad, característicos de la Formación PostPampeano, en un espesor Read more... about Mejoramiento de suelos blandos con columnas de RDC en la Central Térmica de Ensenada Barragán

Buenos Aires Metro Line H, in Argentina runs N-S, at the west side of the city's downtown area. An extension of the line started in 2011. A TBM tunnel and one cut&cover station will be built southbound in estuary soft holocene soils; a NATM tunnel and three cavern stations are being built Read more... about Large Caverns for Metro Stations in Buenos Aires

Buenos Aires, Argentina, is expanding its metro network. Some 17 km of new tunnels have been excavated between 1998 and 2009, and some 20 km are scheduled for construction in the near future. Many major improvements have been implemented during these years in the fields of design and Read more... about Tunnels in Buenos Aires. Development of construction procedures 1998-2009
