<p>The possibility of removing ammonia nitrogen from bioreactor landfill leachate using trickling filter biofilm technology was studied in this thesis.</p>

A theoretical approach to non destructive evaluation of deep foundations using guided waves formulation. Guided wave propagation in infinitely long cylindrical pile embedded in soil is developed from dynamic equations.

This thesis deals with teh analysis and stability of large scale rock slopes in open pit mining and specifically the Aitik open pit mine in northern Sweden. A geomechanical model was developed for the Aitik mine, based on extensive field work and review of ...

The aim of this research was to identify and characterize the small fractures in geothermal rocks using the X-Ray CT scanner.

In part 1 of this thesis, is developed a finite-strain theory for the joint effects of water pumping and surface loads on ground subsidence in a soil system consisting of a hard aquifer sandwiched by two soft and semipervious layers. In the second part of ...

Accurate prediction of rockfalls is practically impossible. Variability in slope geometry, poorly defined initial conditions, uncertain material properties (especially coefficients of restitution) and an analysis method that is sensitive to minor changes in ...

A rock mass is a material quite different from other structural materials used in civil engineering. It is heterogeneous and quite often discontinuous, but is one of the materials in the earth's crust, which is most used in man's construction. This chapter ...

<p>The increasing use of geotextile-reinforced soil systems for important earth structures requires proper understanding of their behavior and validation of the assumptions in their design. Geotextile reinforcement materials are particularly useful in reinforced ...

The aim of 3D stress analysis of underground excavations is to evaluate several alternative schemes for excavation layouts and sequencing so that the most stable configuration and optimum schedule for the excavations can be selected.

<p>A review of behavioral rock properties used for input to the finite element method are summarized in this thesis. Rock properties presented in the literature were primarily obtained from laboratory specimens. Methods to determine applicable field properties ...
