• The development and implementation of an innovative smartphone application to collect route choice preference data 

  Hayes, Gary Patrick (University of Pretoria, 2023-07)

  The research presented in this thesis was motivated by two factors. Firstly, little route choice research has been undertaken in South Africa, especially in urban areas. This has resulted in significant gaps in our ...
• Contribution of matric suctions to the slope stability of tailings dams 

  Basson, Jack Adriaan (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 ...
• Influence of integral bridge abutment stiffness on backfill pressure build-up caused by seasonal temperature changes 

  Havemann, Garfield George (University of Pretoria, 2023)

  Although the construction of integral abutment bridges (IAB) is simplified as the members are all cast monolithically with each other, the soil-structure interaction between the abutments and the retained soil significantly ...
• Development of appropriate synthetic design storms for small catchments in Gauteng, South Africa 

  Mouton, Jacobus van Staden (University of Pretoria, 2023)

  Urban stormwater drainage networks are frequently analysed in dynamic rainfall-runoff simulation models. These models use hypothetical rainstorm events (synthetic design storms) as input in the case of single event-based ...
• Railway condition monitoring using a hybrid multi-view stereopsis and real-time kinematic geolocation pipeline for dense reconstruction 

  Broekman, André (University of Pretoria, 2022)

  Continuous, effective condition monitoring and measurement of railway infrastructure remains a cornerstone of effective maintenance practices. Nonetheless, the potential benefits associated with the rapid advancements in ...

• A comparison of direct and trunk-feeder configurations for bus rapid transit systems 

  Mathebula, Tryphina Lindiwe (University of Pretoria, 2021)

  Bus Rapid Transit (BRT) systems have gained popularity worldwide as a cost-effective alternative to more expensive urban rail systems, carrying around an estimated 33 million passengers each weekday (https://brtdata.org/ ...
• Considering strain compatibility in limit equilibrium analysis for three tailings materials 

  Narainsamy, Yashay (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 ...
• The measurement of soil-water retention curves using the tensiometer method 

  Le Roux, Paul Francois (University of Pretoria, 2019)

  The soil-water retention curve (SWRC) is an essential tool in geotechnical engineering and agriculture used in the analysis of unsaturated soil conditions such as those found in tailings dams and the water retention ...
• Traffic impacts of shared right-of-way public transport systems: A microsimulation-based case study 

  Du Preez, Simeon Johannes (University of Pretoria, 2020)

  Bus Rapid Transit systems are becoming a more integral part of public transport systems in major African cities. Although BRT systems are more versatile than other public transport alternatives, they do require support ...
• Investigating the limitations of the discharge-head relationship of compound crump weirs exceeding their hydraulic capacities 

  Maritz, Ashley Amy (University of Pretoria, 2020)

  The variability of the South African (SA) climate results in abrupt changes in river discharge rates. Compound weirs have been implemented as an attempt to ensure accurate discharge calculations over an extended, but ...
• Seismic performance evaluation of an axially loaded reinforced concrete footing using pseudo-dynamic experimentation 

  Hossell, Shane Michael (University of Pretoria, 2019)

  Southern Africa is characterised as a region of moderate seismicity with several instances of both natural seismicity and mining-related seismicity occurring within the last century. Evaluating the performance of a ...
• Quantifying the economic benefits of gauge changes on the South African core railway network 

  Demmerez de Charmoy, Christian Pierre (University of Pretoria, 2019)

  In its white paper, the Department of Transport proposes a future South African core railway network which requires the conversion and construction of over 8,500 km of standard gauge railway track by 2050. The scale of the ...
• The effect of binder composition and content on the early age behaviour of concrete 

  Visser, Sophia (University of Pretoria, 2019)

  With the increased use of high performance concrete a lower water-to-binder ratio is employed to improve the properties of concrete and mineral and chemical admixtures are introduced. With a low water-to-binder ratio, ...
• The effect of increased axle loading on saturated and unsaturated railway foundation materials 

  Mpye, Godisang David (University of Pretoria, 2020)

  The aim of the research is to investigate the effect of increased axle loading on saturated and unsaturated railway foundation materials for heavy haul applications. The research methodology comprises of a literature review ...
• Investigating the relationship between suction in cement paste and specific concrete properties 

  Schoeman, Mariesa (University of Pretoria, 2020)

  The Soil Water Retention Curve (SWRC) of different soils has been researched thoroughly by multiple Geotechnical Engineers. The interpretation of the SWRC for a specific soil leads to the identification of certain properties ...
• Manufacturing and Performance of Fly Ash Based Synthetic Lightweight Aggregate 

  Hofmeyr, Stuart Grant (University of Pretoria, 2020)

  In South Africa, as much as 33 million tons of ash, a waste product of burning coal, are produced per year. Of the total ash produced, just over 8% is sold for utilisation, the remainder of which is disposed of in landfills ...
• The Effect of Overburden and Horizontal Confining Stress State on Cave Mining Propagation 

  Schoeman, Nicholas Kyle (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 ...
• Performance evaluation of inverted pavements : comparative analysis of South African and Brazilian experiences 

  De Almeida, Damires Cristovão (University of Pretoria, 2021)
