Software for liquefaction analysis and 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 has been used by many universities and agencies internationally, including Albania, Chile, China, Colombia, Greece, Japan, Iran, Israel, Italy, Egypt, Mexico, New Zealand, Saudi Arabia, Turkey, the United Kingdom, and the United States.
LiquefyPro offers multiple methods of calculation. The methods used in the program include: See, Suzuki, Robertson, Tokimatsu, Ishihara, Stark, and Olson methods. Users can use the program’s recommended methods, or more advanced users can select an approach more suited to their local conditions. The calculation includes settlement of wet and dry sand from earthquakes. The settlement is presented graphically along with depth. Factor of safety, liquefied zone, and soil profile are also presented graphically.
Calculation theory and user manual can be downloaded here (in PDF file).
The program is based on the most recent methods recommended by NCEER Workshop and SP117 Implementation. SP117 Guidelines can be downloaded here (in the PDF file, due to file size, use right mouse click to save it to disk instead of directly opening it).
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 copied 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 through Quality Control and Quality
Assurance (QAQC).
