(University of Pretoria, 2023-01)At least 45% of the Merafong City Local Municipality (MCLM) is underlain by dolomite of the Malmani Sub-Group, Chuniespoort Group of the Transvaal Supergroup. The current research area, Khutsong North Townships (KNT’s), ...
-
(University of Pretoria, 2014)Vadose zone hydrology is a developing science influenced by earth scientists (soil scientists, pedologists, hydrogeologists, engineering geologists and geomorphologists) and engineers (geotechnical). ...

(University of Pretoria, 2008)This dissertation collates all available data from the Department of Water Affairs and Forestry’s (DWAF’s) National Groundwater Database (NGDB), DWAF’s Groundwater Resource Information Project (GRIP) and tests conducted ...
-
(University of Pretoria, 2013)The collapse of residual Archaen granitic soils in South Africa is a geotechnical hazard that was identified in the 1950’s. Collapse has led to hazardous building conditions in the rapidly expanding northern parts of ...
-
(University of Pretoria, 2021)The sedimentary rocks of the Karoo Supergroup cover approximately 75% of the surface area of South Africa. Major projects have been constructed on and in these rocks with a number of tunnelling projects such as the Lesotho ...
-
(University of Pretoria, 2012)The Zagros fold-thrust belt results from the continent-continent collision between the Arabian margin and the Eurasian plate following the closure of the Neo-Tethys Ocean during the Tertiary. Despite some ongoing controversies ...
-
(University of Pretoria, 2015)Tropical soils include a wide variety of pedogenic materials common to the tropical regions of the world, of which the material properties and engineering behaviour may vary significantly. These soils in many ways have ...
-
(University of Pretoria, 2013)Dispersive soils are prevalent in many areas of South Africa and the presence of these soils has not only posed a problem in earth dam construction but has led to problems with a number of road projects. The use of dispersive ...
-
(University of Pretoria, 2014)Some validations of and extensions to the Parametric‐Historic procedure as developed in a two‐paper sequel by Andrzej Kijko and Gerhard Graham in 1998 and 1999 are presented. The source‐free distribution they derive is ...
-
(University of Pretoria, 2007-08-14)An estimated 2.5 million people live on dolomite and in excess of 1.2 billion Rands of property damage has been observed to date and in excess of 800 sinkholes have occurred in the Southern Tshwane area alone. Research on ...
-
(University of Pretoria, 2014)Basal reinforcement, where high tensile geogrids are employed beneath structures, is becoming an increasingly accepted construction technique along the eastern coast of southern Africa. The presence of compressible, soft, ...
-
(University of Pretoria, 2018)Slope design and mining in foliated in-situ rock masses can be a major logistical and geotechnical hindrance. The Rock Mass Classification parameters need to be considered in relation to the anisotropic rock masses. What ...
-
(University of Pretoria, 2012)The Gautrain Rapid Rail Link is a state-of-the-art rail route and one of the ten Spatial Development Initiatives planned in Gauteng Province, South Africa. The route comprises two links, namely a link between Tshwane ...

(University of Pretoria, 2000)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2013-05-24)The greater part of land in the area south of Pretoria is underlain by dolomite from the Chuniespoort Group of the Transvaal Supergroup. In South Africa dolomite rock has a notorious reputation for the formation of sinkholes ...
-
(University of Pretoria, 2011-06-27)Geologically complex crystalline aquifers are distributed extensively in Africa and also underlie large parts of the semi-arid Limpopo Province where some of the greatest groundwater needs in South Africa occur. The ...
-
(University of Pretoria, 2019)Faults and dolerite dykes within Basement- and Karoo-aquifers in northern Mozambique may increase groundwater occurrence but may also be barriers to groundwater flow. Should observation boreholes drilled into regional and ...
-
(University of Pretoria, 2007)A new geophysical method was developed to satisfy a need for in-situ density measurements. Various situations, such as a gravity dam wall requires that density measurements should be done without damage to the structure. ...
-
(University of Pretoria, 2012-11-12)Partially saturated soils are often dense with a high bearing capacity and will subsequently only suffer small amounts of compression under normal foundation loads. However, when wetted under load many such soils undergo ...
-
(University of Pretoria, 2018)Mining operations throughout the Bushveld Igneous Complex faces challenges in regards to the safe support of geological structures. Falls of Ground pose a massive risk to safety and production of any underground mining ...
