Abstract:

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 unique characteristics that can mainly be ascribed to the compositions and micro-structures of a material developed under hot, wet soil-forming conditions. Due to the variation in their properties and behaviour, the classification of soils formed under such conditions as distinct and well-defined soil types appears to have been avoided in the past. Unfortunately, this has brough

The Wakatipu Basin lies within the Otago Schist belt, and aggregates derived from the schist do not meet New Zealand basecourse specifications. This study comprises engineering geological investigations of the roading aggregate with the objective of identifying potential aggregate source areas which comply with specifications. Five aggregate sources, two glacial and three post-glacial, have been identified, and their geology related to aggregate quality. A survey of existing aggregate quarries confirmed the sub-specification quality of schist derived roading aggregate, and that the highest qu

Abstract:

Whitehall Quarry is located 4 km east of Karapiro, near Cambridge within the Waikato District. Current quarrying operations produce between 150,000 and 300,000 tonnes of aggregate for use in the surrounding region. This study is an investigation into the engineering geological model for the quarry and pit slope stability assessment. Pit slope stability is an integral aspect of quarrying and open-pit mining since slopes should be as steep as possible to minimise waste material which needs to be removed, yet shallow enough to minimise potential hazards to personnel and equipment below pit slopes

Thus it appears that the index could be applied to various styles of mineralization and orebody morphology.<br>The complexity classification was designed to aid in geologic control and subsequently improve mining method performance.

Sulfur-species in geological materials have detrimental consequences for geoenvirormental engineering.

Based on this zonation, a targeted sampling strategy for sulfur-species is presented and permits application of exis

Abstract:

<p> Fractures are often leakage pathways for fluids through low-permeability rocks that otherwise act as geologic barriers to flow. Flow of fluids that are in chemical disequilibrium with the host rock can lead to mineral precipitation, which reduces fracture permeability. When fracture surfaces contain a single mineral phase, mineral precipitation leads to fast permeability reduction and fracture sealing. However, the feedback between precipitation and permeability may be disrupted by mineral heterogeneities that localize precipitation reactions and provide paths of low-reactivity for fluids

Abstract:

<p> Unstable failure in underground mining occurs when a volume of material is loaded beyond its strength and displaces suddenly. It is recognized on various scales, from small rock bursts to the collapse of pillars or entire sections of a mine. The energy that is released during smaller scale events is manifested through the ejection of material, which can pose a hazard to the safety of miners. Larger scale events generate seismic waves as mine workings are damaged and may entrap miners or terminate production. </p><p> This dissertation focuses on the analysis of unstable failure in an

Abstract:

<p> Geothermal energy has the potential to become a substantially greater contributor to the U.S. energy market. An adequate investment in Enhanced Geothermal Systems (EGS) technology will be necessary in order to realize the potential of geothermal energy. This study presents an optimization of a waterbased Enhanced Geothermal System (EGS) modeled for AltaRock Energy’s Newberry EGS Demonstration location. The optimization successfully integrates all three components of the geothermal system: (1) the present wellbore design, (2) the reservoir design, and (3) the surface plant design. </p

Abstract:

<p>The Sandia GeoModel is a continuum elastoplastic constitutive model which captures many features of the mechanical response for geological materials over a wide range of porosities and strain rates. Among the specific features incorporated into the formulation are a smooth compression cap, isotropic/kinematic hardening, nonlinear pressure dependence, strength differential effect, and rate sensitivity. This study attempts to provide enhancements regarding computational tractability, domain of applicability, and robustness of the model. A new functional form is presented for the yield and pla

Abstract:

This master thesis has interest in analyzing the two unstable rock slopes Ivasnasen and Vollan. These rock slopes are located in a U-shaped valley in Sunndal municipally (Møre & Romsdal, western Norway). The analyses are based on a combined approach using detailed geomorphic, structural and geological field mapping. This along with interpretation of high-resolution digital elevation models (DEM) and orthophotos, LIDAR-scans from one of the sites (Ivasnasen 2010 and 2011), numerical analysis, kinematic analysis, XRD analysis and laboratory testing. The two sites, Ivasnasen and Vollan a

Abstract:

This study investigated the characteristics of 26 failed and non-failed landslide dams (Murchison dataset) formed in the northern part of the South Island, New Zealand, from the 1929 Murchison and 1968 Inangahua earthquakes. The dataset was compiled from a combination of engineering geological mapping, field investigations, aerial photography interpretation and a review of existing literature. Current analysis techniques have been applied to the investigated landslide dams to assess their ability to accurately predict the post-formation development (or ‘evolution’) of the dam overtime.
