Software for liquefaction analysis, Software for settlement
analysis by liquefaction: Liquefaction of saturated soils
(silt, sand, and gravel) during earthquakes has caused severe damage
to buildings, earth embankments, dams, and bridges. LiquefyPro
assists engineers in evaluating liquefaction potential and earthquake-induced
settlement. It determines the liquefaction zone and settlement
under earthquake conditions.
It is a Windows-based program with graphical presentations for geotechnical
reports. It will be a valuable addition to your software library.
LiquefyPro gains international reputation and has been used
by many universities and agencies in many countries including Albania,
Chile, China, Japan, Iran, Israel, Italy, Egypt, Mexico, New Zealand,
Saudi Arabia, Turkey, Colombia, Greece, United Kingdom, and United
LiquefyPro offers multiple methods of calculation. The Methods
used in Program are including: See, Suzuki, Robertson, Tokimatsu,
Ishihara, Stark, and Olson methods. Users can use recommended methods
by program, or more advanced users can select an approach more suited
to their local conditions. The calculation includes settlement due
to earthquake from wet sand and dry sand. The settlement is presented
in graphics along with depth. Factor of safety, liquefied zone, and
soil profile are also presented in graphics. Calculation
theory and users manual can be download here (in PDF file).
The program is based on the most recent methods recommended by NCEER
Workshop and SP117 Implementation. SP117

The program reads SPT or CPT data through MS-Excel. If Fines Contents
is not available, the program can automatically generates Fines% from
CPT data. The graphics can be saved in Windows Metafile or copy to
your clipboard, which can be used for other applications such as Excel,
Word, and AutoCAD.
The program can determine the results of ground improvement by adding
fill on the surface. The liquefaction potentials before and after
fill can be calculated and presented.
If you are still using spreadsheets for your liquefaction analysis,
you should make the change now. LiquefyPro goes beyond the
limitations of spreadsheets. It provides the most recent calculation
methods and accurate results. It also provides many methods for your
comparison. The settlement calculation is difficult to do in spreadsheets.
Data from spreadsheets or testing results can be imported or pasted
into the program. The software was fully checked for its accuracy
and correctness thorough Quality Control and Quality Assurance (QAQC).
