The bearing capacity of shallow foundations is a traditional problem in geotechnical engineering. Many authors have contributed to the solution of this problem using an equation valid under ideal conditions, such as strip foundation under vertical and centred loading and assuming the superposition of the separate effects of self-weight and surcharge. Su...
View ArticleA series of laboratory tests were conducted on matched rock joint samples, no larger than 16 x 16 cm2 of section, which were extracted from an artificial joint, having 4.32 m2 in area, carved in a porphyritic granite block. These tests (1200 pull tests and 200 trials conducted in a sliding machine) involved the systematic levelling of sample middle plan...
View ArticleThe Pinalito main hydroelectric tunnel, with a length of 11 km, is located in Cordillera Central mountain range, Dominican Republic. This mountain tunnel has been mined through extremely fractured andesitic-basaltic and rhyolitic tuffs. These rocks are been subjected to shear and collisional displacements between Caribbean and North America plates since...
View ArticleThis paper deals with Plaxis 3D finite element simulations of the mechanical response of deep foundations founded in a collapsible tropical soil. Main attention is initially paid to differences between single continuous flight auger (CFA) pile behavior and the behavior of CFA piles in standard groups. The numerically computed load-settlement curves are ...
