The GeoStudio suite includes eight products:

**SLOPE/W**
**Basic**

The slope stability analysis features and capabilities in GeoStudio Basic are more than adequate for conventional analysis of most natural slopes and man-made cut slopes that may be encountered in routine engineering practice. The 10-region and 10-material limit in GeoStudio Basic is more than sufficient to describe the geometry and stratigraphy of common slope stability problems.

Methods that can be used to compute safety factors include the Ordinary, the Bishop Simplified, the Janbu Simplified, the Spencer and the Morgenstern-Price method. As well, the advanced General Limit Equilibrium (GLE) method is available, which is sometimes useful for helping with interpreting the results of the various methods.

Reinforcement can be simulated in a simplistic way
with the use of concentrated line loads. This is an
adequate and acceptable approach for determining the
forces the reinforcement needs to provide to achieve
a design factor of safety against the possible slip
of the retained soil wedge. Once the required force
is known, the details of the reinforcement can be
selected and designed independent of the stability
analysis.

**SEEP/W****
Basic**

The SEEP/W Basic Edition can be used for the
analysis of confined and unconfined steady-state
seepage problems. The features available are more
than adequate for the analysis of classical problems
such as confined seepage flow below a structure with
a cutoff and unconfined flow through an earth
embankment.

More data points can be
used to describe the conductivity function, but a
two-point approximation is adequate for most
practical steady-state seepage problems where there
is a significant component of lateral flow as
through an embankment, for example.

The SEEP/W Basic
computed seepage results can be used directly in a
SLOPE/W Basic slope stability analysis, if a
piezometric line is not adequate to describe the
pore-pressure conditions of a particular problem.

**SIGMA/W **
**Basic**

SIGMA/W Basic is particularly useful for estimating
the immediate or elastic settlement of multilayered
systems. A typical case is the immediate settlement
of a round fluid storage tank as illustrated here.

SIGMA/W Basic can also be used
to perform saturated consolidation analyses.
Consolidation
analyses of a multilayered system are nearly
impossible to do with hand-calculations even if it
is a one-dimensional analysis. Such 1-D analyses can
be done with relative ease with SIGMA/W Basic.

The full-featured edition of SIGMA/W is required for
non-linear deformation analyses and stage (time)
dependent boundary conditions.

**QUAKE/W **
**Basic**

QUAKE/W Basic is restricted to linear-elastic
material properties which limits its use in actual
field problems. Using only linear-elastic material
properties tends to over estimate the dynamic
response of earth structures to earthquake shaking.
This can lead to unrealistic motions and excessive
dynamic stresses.

Dynamic linear-elastic analyses
however are useful for investigating and
demonstrating how QUAKE/W analyses are performed,
what material properties are required and how the
results can be visualized. In addition, QUAKE/W
Basic is useful for demonstrating how the QUAKE/W
results can be used in SLOPE/W to do a Newmark-type
permanent deformation analysis and for determining
how the factor of safety varies during an
earthquake.

**TEMP/W **
**Basic**

TEMP/W Basic is intended primarily for the analysis of ground freezing and thawing problems with limited geometric complexity and with constant thermal boundary conditions.

**CTRAN/W **
**Basic**

CTRAN/W uses the flow velocities from a
steady state SEEP/W analysis to
model the migration of
contaminants.
So, the CTRAN/W Basic
limitations are primarily the limitations inherent
in SEEP/W Basic.

CTRAN/W Basic is particularity
useful for tracking
the paths of imaginary
contaminant particles in time and space. The
particles can be tracked forward from a source to a
discharge point or backward from a discharge point
to the source. Travel times and distances are
computed for each particle.

In addition, CTRAN/W Basic is a useful tool for investigating pure dispersion and advection-dispersion problems, particularly one-dimensional problems.

**AIR/W **
**Basic**

AIR/W is for analyzing air flow through soil. The
primary intent is to examine how air flow and air
pressure affect water flow and pressure. This makes
it possible to look at the true matric suction term
(ua–uw).

AIR/W Basic is limited to steady-state
conditions, but is powerful enough to include
modeling a vapor extraction well under long term
pumping conditions, for example. You could specify
atmospheric pressure along the ground surface and a
vacuum air pressure at the screen of a well. The
results would show a drawdown cone of water in the
soil, as well as a steady state mass flow rate for
the air leaving the well.

**VADOSE/W Basic
**Using VADOSE/W
Basic, you can analyze 1D flux boundary problems
such as:

˙Design and performance monitoring of single or multi-layered soil covers over mine and municipal waste facilities

˙Development of climate controlled pore-water pressure distributions on natural or man-made slopes for use in stability analyses

˙Determining infiltration, evaporation and transpiration rates resulting from agriculture, irrigation projects, or natural systems

˙Predicting oxygen or radon gas diffusion and decay through the vadose zone

˙plus many more!

VADOSE/W Basic pore-water pressures can be used in a CTRAN/W Basic contaminant transport analysis.
