Newest software
EasyRefract
EasyRefract is the new software from GeoStru Software
dedicated to the interpretation of seismic refraction tests using
the reciprocal method and the generalized reciprocal method (G.R.M.).
The definition of the stringing profile is
extremely
flexible and does not
impose constraints
on the number of blows to be
used in the analysis.
The software is able to guide the user through the analysis phases
offering the full control of the operative process.
The
program has
implemented an efficient tracking system
that allows editing the
aerial photo of the research area.
Field data
is
extracted directly from the files
generated by
loggers (in formats like
SEG2, SEGY, SU, etc.)
and plotted
to give the user the
identification of the early
arrivals, that can also
be entered manually or by
copy/paste.
As a function of the identification
of the first arrivals,
the software is able to operate
the regression analysis
and identify the time travel graph. Through this
analysis phase arrival
times are assigned to the
correct refractors.
After building the
time travel graph
and having identified the
propagation speed of the seismic signal
in the different layers
of the soil, the
Generalized Reciprocal Method is applied.
This method is based on the research, in the time-distance diagram,
of an optimal distance between geophones XY, in such way that the
seismic rays coming from opposing
energization points,
positioned
in a symmetrical manner
at the ends of the
stringing, arrive from the same point of the refractor on the
geophones placed in X and Y.
In addition to performing an automatic search of the optimal XY,
EasyRefract
provides, for the eligible values XY, the graph of velocity function
with the standard deviation for each associated regression and the
graph of the time-depth function with
the roughness value.
