- Real-time waveform display while testing
|
|
|
|
|
|
- Accuracy and resolution for these methods are constant for all test
depths, whereas the accuracy and resolution of the surface methods
decreases with depth
|
|
|
|
|
|
- P-SV source used in CS tests can impact in the vertical, transverse,
and radial directions
|
|
|
|
|
|
- Correlation between CS and Spectral Analysis of Surface Waves (SASW)
tests on soil sites showed that the values from both tests typically
compare within a 10-15% difference
|
|
|
|
|
|
- CS method is the most accurate method for determining material properties
of rock and soil sites
|
|
|
|
|
|
- Acquisition and processing software are easy to use, yielding fast
and accurate results
|
|
|
|
|
|
- Thin layers, which are often invisible to surface methods, can be
detected with CS/DS investigations
|
|
|
|
|
|
- Sources and receivers can be oriented with inclinometer casing dummy probes
