Soil Dynamics In-Situ

Field tests can measure the soil response in situ where the ground is not disturbed and the in-situ conditions are preserved.

The most common in-situ tests are the following:

• Seismic Reflection Test
• Seismic Refraction Test
• Seismic Cross-hole Test
• Seismic Down-hole /Up-hole Test
• Surface waves Method (such as Spectral Analysis of Surface Waves, SASW, or Multichannel Analysis of Surface Waves, MASW)
• Seismic Cone Penetration Test (SCPT)

The Surface Wave Method, but also Seismic Reflection and Seismic Refraction tests are widely used as they do not require boreholes or penetrations into the ground which can be time-consuming and expensive. Therefore, they are simple and low-cost solutions.
