Multichannel Analysis of seismic waves
Shear Wave velocity ( Vs). Vs is one of the elastic constants , ( Young’s modulus). V
Vs is an indicator of the ground strength (stiffness) and load-bearing capacity.
A method to map soils strength without drilling.
Measure the Shear wave velocity of the soils using a geophysical survey and very smart processing.
Fill in gaps between drill holes – corelate to SPT hammer data and soil strength data.
A very powerful and fast geophysical method.
Active mode – to 25m
Passive mode to more than 100m. No need for sources uses natural ground noise source
MASW is a non-destructive method use advance or as adjunct to drilling to give soil and rock depth and soil strength.
