At Solvay Mine, located in southwestern Wyoming, a subhorizontal trona seam is mined at depths of between 460-490 m using mechanized room-and-pillar and longwall mining methods. The stratigraphy at the mine generally ...

A rock bolt installed in field has only one short exposed end on the rock surface. This condition has posed challenges in field instrumentation and made it difficult to use the ultrasonic guided wave method for rock bolt ...

Residual stresses are known to exist within the microstructure of crystalline materials as a result of material formation processes and exists in a state of equilibrium with their own internal forces. Research has ...

Pillars are important support elements in underground mines. A reliable design of hard rock pillars requires a thorough understanding of their strength and failure mechanisms. While several investigations have been conducted ...

The heterogeneous composition of the lithosphere affects the way it deforms under extension. This thesis investigates the effects of heterogeneities that introduce compositional, thermal, and thickness contrasts within an ...

Although many studies have been conducted on the structural behavior of concrete-filled fiber-reinforced polymer (FRP) tube (CFFT), the soil-structure interaction of CFFT piles was not previously considered. In this study, ...

This thesis applies finite element numerical modeling to a range of projects investigating salt tectonics at rifted continental margins. Both two-dimensional and fully three-dimensional models are used. The first project ...

Integral Abutment Bridges (IABs) are well known for their lower construction and maintenance costs by eliminating expansion joints and bearings. The flexible piles supporting the end-span abutments offer the possibility ...
