In this thesis a novel conceptual model of the mechanics of sands is developed within an elastic-plastic framework. In this study is presented an extension of the critical model by incorporating the features of granular fabric.

<p>The construction of underground tunnels in soft ground in urban areas involves the potential for ground movements caused by the tunnelling to affect existing surface structures. Masonry structures are at particular risk of crack damage. Conventional empirical ...

This dissertation discusses the evolution of mountains, particularly the interaction between uplift, which is controlled by horizontally-directed plate tectonic and vertically directed isostatic forces, and erosion, which encompasses glacial, periglacial, ...

The overall objective of this thesis is to mitigate methane emissions from landfills. To reach this objective, a test site was selected to evaluate the effects of compost placement over a closed landfill. The static chamber technique was used to estimate methane ...

This thesis intends to extend and improve the database on seismic properties available on mantle rocks.Further, the relevance of different olivine CPO types is discussed and the influence of hydrous phaseson the seismic properties is investigated. Ten samples ...

The study presented here examines six full-scale bioreactor projects with the objective of providing a perspective of current practice and technical issues that differentiate bioreactor landfills from conventional landfills.

In this thesis, the results of a number of rock mass classification systemsapplied to Dim-highway tunnel study area are presented. The tunnel ground was classified according to Rock Mass Rating (RMR), Modified Rock Mass Rating (M-RMR), Rock Mass Quality (Q,) ...

Triaxial testing has been used for many years by geotechnical engineers, to monitor the response of soils to varying stress conditions. Similarly, Hot-Mix Asphalt (HMA) has been tested, using triaxial systems, to determine the reaction of the material to both ...

This thesis presents an approach based on Bayesian decision analysis for handling uncertainties and evaluating alternative actions at contaminated sites. These actions include remediation, investigation and protection strategies for contaminated soil and groundwater ...

This thesis investigates an example of natural lineation variation in three segments of the Sierra Crest shear zone system, Sierra Nevada, California.
