SPT Correlations Software – NovoSPT
The Standard Penetration Test (SPT) is the most popular and economical test for evaluation of subsurface information, both on land and offshore. This test is widely used to obtain the bearing capacity of soil for shallow and deep (pile) foundations. Blow counts (N) measured in the field are corrected for rod length, borehole size, sampler type, and hammer energy level. The corrected blow counts (N60) are then used for estimation of various soil properties and bearing capacity.
NovoSPT is a powerful, user-friendly geotechnical software for correlating soil properties from SPT blow counts. We have gone through more than 70 published papers and geotechnical reference books and collected over 300 SPT correlations with various soil properties.
NovoSPT comes with a complete help file (accessible from inside the program), and user’s manual in PDF and eBook formats to allow you getting up-to-speed in a very short time.
Correction of SPT Blow Counts
The program automatically applies the following corrections on SPT field data (N) to obtain N60 and N1(60):
- Borehole Size
- Sampling Method
- Rod Length
- Energy Level
- Overburden Stress Corrections (covers 9 methods)
- Water Level Correction (optional – for bearing capacity analysis when N60≥15)
Use The Right Correlations!
Every correlation is developed for certain soil type(s). NovoSPT knows that. At a specific depth, based on the site stratigraphy NovoSPT only used the correlations that are developed for that type of soil. We have categorized the soil types as Clay, Silt, Sand and Gravel. Each correlation may be valid for one or a combination of these soil types.
Bearing Capacity Analysis
Using NovoSPT you can estimate bearing capacity of pad / strip footings based on SPT blow counts.
