This work analyses the influence of footing size and soil matric suction on the behavior of shallow foundations on unsaturated sandy soil, in terms of bearing capacity and settlements. Fourteen plate load tests were performed at the Experimental Site of USP/São Carlos. Rigid metal plates were used, with diameters varying between 0.20 m and 0....
View ArticleThe Hoek-Brown failure criterion was developed in the late 1970s to provide input for the design of underground excavations. Bieniawski’s RMR was originally used to link the criterion to engineering geology input from the field but a more specific classification system called the Geological Strength Index (GSI) was introduced in 1995. Both the...
View ArticleThe mining industry worldwide has typically not conducted the development of mines with the overall design objective of a safe, environmentally sound and aesthetically satisfactory post-operational mine-site. Mine waste has typically not been engineered to any large degree but has rather been disposed of in the easiest or most cost effective manner with...
View ArticleAmong all the constructive elements in waste containment systems, base liner may be the one of greatest concern. In Brazil, the use of compacted lateritic soils for this purpose is widely accepted due to their wide occurrence. While they usually achieve compaction and strength requirements, sometimes they may need some improvement in terms of hydraulic ...
