Modelling and testing Modélisation et expérimentation David Muir Wood School of Science, Engineering, University of Dundee, United Kingdom, [email protected] ABSTRACT: All soil testing is performed in the context of an implicitly or explicitly assumed (constitutive) model for the soil. The interface between modelling and testing is challenged by deficiencies of the testing and by deficiencies of the model. Many testing configurations lead to inadvertent or inevitable inhomogeneity, so that a soil samples behaves as a system and not a single element. But models are appropriate simplifications of reality and are inevitably deficient. The more severe the deficiency the harder it becomes to calibrate the model against experimental data. Even for more elaborate models, the conjectures on which they are based are rarely subjected to testing regimes which deliberately set out to refute those conjectures. No matter how extensive our testing of a model against laboratory data, a subsequent application will certainly take it into an unknown region in which it is to be hoped that no unintended instabilities will appear. RÉSUMÉ : Tous les essais de mécanique de sols sont effectués dans un contexte d’existence d'un modèle du sol implicitement ou explicitement supposé. -

ISSMGE Bulletin: Volume 7, Issue 5 Page 8584 ISSMGE AFRICA REGION “THE PAST” Dr Peter Day (South Africa) assisted by Dr Mustafa El-Ghamrawy (Egypt) and Prof Mounir Bousida (Tunisia) GOING WAY BACK A 42cm x 2,8m papyrus scroll discovered around 1820 near ancient Thebes in Egypt, and now in the Egyptian Museum in Turin, is purported to be the world‟s oldest surviving geological map. It depicts the topography and geology of Wadi Hammamat in the mountains of the central Eastern Desert of Egypt, including the aerial distribution of sedimentary and igneous/metamorphic rocks. It also shows the gold workings at Bir Umm Fawakhir, the gold-bearing quartz veins on the adjacent mountains and the lithologically diverse wadi gravels. This map, which was drawn during the reign of Ramesses IV (1151 – 1145 BC) pre-dates the next oldest known geological map by some 29 centuries [1]. Remaining in Egypt, various accounts of the construction of the Giza pyramids refer to the use of massive earth ramps for hauling great blocks of stone to incredible height. It is therefore clear that Africa‟s interest in things geological and geotechnical dates back to ancient times. At the other end of the African Continent, the first comprehensive geological map of South Africa was published by the Geological Society of London in 1856. It was compiled by the Scottish-born pioneer of the Cape mountain passes, Sir Andrew Geddes Bain. He and his son, Thomas, constructed no less than 32 major passes in the Cape Province of South Africa during the 19th Century [2]. -
