In the case of skyscrapers, the suitable bearing surfaces occur at considerable depth in rock formations, and when it is uneconomical to excavate the overlying weak material, socketed shafts are required for the foundations. In selecting a suitable foundation system, several factors must be taken into consideration. In this article problems associated t...
View ArticleThe influence of soil drill rod length on the N value in the SPT-T test has been studied extensively by Mello (1971), Schmertmann & Palacios (1979), Odebrecht et al. (2002) and Cavalcante (2002). This paper presents an analysis of the Standard Penetration Test supplemented with torque measurement (SPT-T). A theoretical study of the resistance of...
View ArticleThe 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...
