(University of Pretoria, 2015)Opencast mining has been and continues to be a favoured method for the extraction of the vast coal reserves in the Highveld of South Africa. Previously backfilled and restored open cast areas are generally zoned for ...
-
(University of Pretoria, 2020)In geotechnical engineering, the soil type which has had some of the most severe economic implications is that of swelling clays. Swelling or expansive clays form a subgroup within the field of unsaturated soils which ...
-
(University of Pretoria, 2016)The study comprised the modelling of embankments on a heavy haul coal export railway line between Ermelo and Richards Bay in South Africa. The design of these embankments is usually done with slope stability analysis? ...
-
(University of Pretoria, 2018)Conventional concrete road pavements are widely used and their behaviour is reasonably well understood and readily predictable, generally by means of semi-empirical design methods. An alternative pavement type, referred ...
-
(University of Pretoria, 2021)Recent tailings dam failures around the world have highlighted the real risk posed by undrained slope failures. Undrained failures are fundamentally different to drained failures in the sense that different mechanisms are ...
-
(University of Pretoria, 2023-06-01)The strengthening effect of matric suctions is typically ignored in slope stability analyses. This is due to the uncertainty in the magnitude and reliability of in-situ matric suctions and the effect thereof on the shear ...
-
(University of Pretoria, 2018-02-01)Integral bridges are designed without expansion joints or bearings to eliminate the maintenance and repair costs associated with them. Thus, the expansion and contraction due to daily and seasonal temperature variations ...
-
(University of Pretoria, 2020-09-28)The mechanism of cave mining propagation still requires a better understanding to be attained outside the industry-accepted Duplancic conceptual model. While this model suggests a continuous damage profile to be followed ...
-
(University of Pretoria, 2017)Civil structures are founded on or within soil. Understanding the interaction of a structure with the soil it is founded on or within is vital for designing and constructing structures that will be safe and functional for ...
-
(University of Pretoria, 2019)Approximately a quarter of South Africa’s Gauteng Province is underlain by dolomite, a carbonate rock which is susceptible to dissolution and therefore sinkhole formation. Current design codes for developing on dolomitic ...

-
(University of Pretoria, 2015)As a result of the mining that has taken place over the last century in South Africa, many towns and cities have developed around mining hubs, the most significant of these being the city of Johannesburg. Over the years, ...
-
(University of Pretoria, 2017)Limit equilibrium methods are widely and routinely used in practice. In several codes, limit equilibrium methods are recommended to evaluate the stability of a lateral support systems, such as soil-nails and anchors, to ...
-
(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, 2015)Foundation systems are some of the most widely used structures in civil engineering. The design thereof is governed by two failure mechanisms, either bearing capacity failure or settlement failure. Generally, the governing ...
-
(University of Pretoria, 2017)The theory of soil arching can aid a study into the field of sinkhole development to enable researchers to understand possible mechanisms that may mobilise in the overburden material when existing underground cavities ...
-
(University of Pretoria, 2017)In geotechnical practice, soils are generally assumed to have negligible tensile strength. However, in the context of unsaturated soils, this strength can be significant and important to consider. In contrast to the two-phase ...
-
(University of Pretoria, 2020)Pile foundations are extensively used to support various structures that are constructed in soft/loose soils, where shallow foundations would be considered ineffective due to low bearing capacities and large settlements. ...
-
(University of Pretoria, 2017)Continued population growth is placing strain on the waste disposal facilities available in South Africa. However, limited air space suitable for landfilling drives the need for alternative solutions such as piggyback ...
-
(University of Pretoria, 2022)Since the rise of geosynthetics in industry and the subsequent challenge posed to conventional steel reinforcement, it was pertinent to directly compare the performance of a soil wall reinforced with two different types ...
