Background

Bill Haneberg has used Mathematica on NeXT and Macintosh systems to solve research and consulting problems in geomechanics, engineering geology, and hydrogeology since 1989. Many of these solutions have been described in peer-reviewed papers and presented at major scientific meetings. Bill has also used Mathematica as a teaching tool in graduate-level classes in geomechanics. In 1999 he left a senior research position at the New Mexico Bureau of Mines and Mineral Resources to establish a consulting practice based in the Seattle area.

Mathematica Applications and Experience

Slope Stability
- Derivation of first-order, second-moment expansions and Monte Carlo simulations for probabilistic analysis of the stability and reliability of forested slopes with variable pore water pressure
- Development of spatially distributed (GIS-style) methods for reconnaissance-level probabilistic slope stability analysis
- Evaluation of the effects of blasting on the stability of steep, colluvium-mantled slopes
- Calculation of rockfall velocity and kinetic energy at impact
- Coupling of analytical solutions for stresses in an elastic half-space with topography and steady groundwater flow to evaluate the influence of topography and regional state of stress on Coulomb failure potential of granular soil
Hydrogeology
- Derivation and plotting of analytical solutions to simulate the influence of faults on groundwater flow, including the role of faults as groundwater sources/sinks
- Development of linear pore pressure diffusion models and lumped parameter mass balance models to understand the influence of storm duration/frequency, storm intensity, and antecedent soil moisture conditions on precipitation-induced pore water pressure changes in potentially unstable hillsides
- Multidimensional curve fitting and plotting of void ratio, confining stress, and stress-dependent permeability data
- Time series analysis of water-level data
- Visualization of results from finite difference flow models
Geomechanics
- Derivation, evaluation, and visualization of analytical solutions for stresses and displacements in compressible elastic layers and multilayers draped over buried discontinuities (e.g., drape folds)
- Development of first-order accurate analytical solutions for stresses and displacements in compressible elastic half-spaces with topography and variable regional states of stress (Applications of these solutions have included evaluation of the effects of valley incision on the subsurface state of stress and degree of overconsolidation in underlying clastic aquifer systems and evaluation of the influence of valley shape on modes of coal mine roof failure.)
Geophysical Log Analysis
- Nonlinear fitting of Athy and Dickinson depth-porosity curves to digital geophysical logs, which were then used to predict aquifer compressibility and specific compaction, using Helm's porosity gradient method
- Variogram calculation to characterize the spatial variability of geophysical log porosity within and among lithofacies
- Calculation of derivative geophysical logs (e.g., Young's modulus, electrical conductivity) from standard log suites
- Cross-plots for visualizing relationships among log parameters
Structural Geology
- Modeling the influence of mineralogy on frictional heat dissipation near faults, with implications for the origin of pseudotachylyte
- Characterization of fabric and permeability anisotropy of faulted sands
- Use of equal-area projection properties to generate populations of randomly oriented fracture data
- Development of analytical solutions for three-point problems
Custom Graphics and Scientific Visualization
- Principal stress orientations/magnitudes
- Displacement vector fields and deformed meshes for solid mechanics modeling
- Borehole geophysical log data sets
- Microradian-sensitivity tiltmeter data
- Cumulative distributions and results of Kolmogorov-Smirnov tests
- Spatially distributed slope stability analysis results superimposed on digital elevation models
