This software performs
Dynamic Penetrometry, that is the reading, recording,
interpretation, storage and the
management of any type of
penetrometer including new or
personalized equipment and of in
borehole SPT readings.
Dynamic Probing
provides functions for an archival
of readings by site and for
automatic calculation of the real
energy transmitted, including
correction for warp, and of the
correlation coefficient with SPT
(Standard reference for geomechanic
calculations and geotechnic
correlations).
Processing of data is instantaneous,deriving
the values of Ndp & Rd and
immediately generating a graphic
display. In addition, the software
proposes discrete layer boundaries,
and enables bitmaps or colors to be
assigned for lithologic coding. In
geotechnic calculation for coherent
and incoherent terrains, several
correlations are available for
diverse lithologic types, which
provide a more precise ‘geotechnic
calibration’ for the specific trials
zone.
Dynamic Probing enables the export
of graphics in DXF or XLS, provides
bearing capacity calculation with
diverse foundation geometries (beam,
plinth, mat, etc.), relative
settlements, verification of piles
and definition of the liquefaction
potential in terrains subject to
seismic forces.

READINGS PROCESSING
Dynamic Probing features a clear
and straightforward processing of readings obtained
on site.
New readings may be inserted at any point, assigning
the cartesian position coordinates (X and Y), the
initial depth (Z), the final depth, the ground water
table depth if any, as well as the date. For each
site an indefinite number of readings may be
recorded and the correlations suggested developed.
Each reading is easily identified visually thanks to
the legend and display graphics of dynamic
resistance and number of blows
DATA ENTRY
As the user enters the number of blows for
each penetration step, the sampler bit coefficient,
reduced, and non reduced, dynamic resistance on the
layer are calculated; concurrently a bar diagram for
the number of blows and a graphic representation of
the progress of dynamic resistance are shown .
CORRELATIONS
The geotechnic parameters of particular significance
for terrain characterization may be indicated by the
user. The litho logic cases that originate the
numerous correlations accompanying the program,
enable the user to characterize an extensive variety
of terrains. The user is further provided with tools
to select for use those correlations judged to most
nearly reflect to the litho types actually
encountered. The parameter that are the outcome of
the computation:
Cohesive terrains
Undrained cohesion (Terzaghi-Peck, SUNDA

(1948), U.S.D.M.S.M., Schmertmann (1975), Fletcher
(1965), Houston (1960), Shioi - Fukui (1982),

Edometric modulus (Stroud e Butler (1975), Vesic
(1970), Trofimenkov (1974), Mitchell e Gardner,

Young's modulus (Schultze-Menzenbach, D'Appollonia
ed altri 1983)

Menzenbach (1961))
Friction angle (Peck-Hanson-Thornburn-Meyerhof

Liquefactive potential (Seed (1979))
Ko modulus (Navfac (1971-1982) )
COMPUTATION
For each sampling, based on the user selected soil
type (Cohesive or Non cohesive), computation is
performed layer by layer. Thereafter for each layer
the parameters of all the proposed correlation
parameters are calculated, particularly highlighting
the ones favored by the user.
For each layer, the number of blows, depth, the
correlation applied, and the calculated geotechnic
parameter value may be exported.
BEARING CAPACITY AND LIQUEFACTION
Dynamic Probing calculates the bearing
capacity and settlement of surface foundations
utilizing a number of methods and additionally
calculates the liquefaction potential of non
coherent layers.
SECTIONS IN DYNAMIC PROBING
Dynamic Probing enables the automatic generation
sections from test data using the 'Sections' module.
A command enables the selection of those tests on
which the generation of the sections is based and to
open the new application. (The same procedure can be
used from the GeoStru program 'Static Probing'; the
counterpart of Dynamic Probing for Static
penetrometers).
The Sections module is actually a stand alone
section editor within, which sections can be created.
Further it enables an import of stratigraphic
columns originating from the GeoStru programs 'Stratigrapher'.
'Sections' is interfaced with GeoStru program
Slope,such that the sections
generated can be read as input by this program in
order to perform an analysis of their stability.
