Correlations Between Dynamic Probe Blow Count And Undrained Shear Strength For Peat At A Well-Characterised Raised Bog In Ireland, David Mchugh, Ciaran Reilly, Juan Pablo Osorio
Correlations Between Dynamic Probe Blow Count And Undrained Shear Strength For Peat At A Well-Characterised Raised Bog In Ireland, David Mchugh, Ciaran Reilly, Juan Pablo Osorio
Articles
Peat deposits are generally heterogeneous, with large variations over small areas. Peat has an extremely high water content, high compressibility and low shear strength. This presents a major issue in studying the geomechanical behavior of peat. For this study, field and laboratory tests were conducted to establish the undrained shear strength (su) of peat at a cutover industrial peatland in Ireland which had been extensively characterized in the past. The new field work included TRL-type Dynamic Cone Penetrometer, Mackintosh probe and field vane shear tests. A correlation was developed between the Mackintosh probe “M-value” blow count and the …

Propiedades Geotécnicas De La Turba Intervenida Antrópicamente, Juan Pablo Osorio

La intervención antrópica en turberas genera cambios significativos en las propiedades geotécnicas de un material orgánico, altamente compresible y con baja resistencia al esfuerzo cortante. Existen diferentes formas de intervención, dependiendo de las tradiciones de cada lugar. Sin embargo, los procesos de intervención más comunes son la precarga por medio de terraplenes y el drenaje, las cuales generan una reducción en el contenido de humedad, la compresibilidad y la permeabilidad, así como un incremento en la resistencia al esfuerzo cortante. En el presente artículo, se discute el efecto de la intervención antrópica en las propiedades geotécnicas de las turbas, a …
