Accurate shear wave velocity profiles have been long recognized as essential data to evaluate the dynamic response of soil deposits and soil-structure interaction under earthquake and other forms of dynamic loading. The determination of shear wave velocity profiles is especially important for port design in seismically active locations. The advantage of obtaining shear wave velocity profiles by in situ non-intrusive surface wave measurements, especially in hard-to-sample soils, has been well recognized. The paper presents the controlled source spectral analysis of surface waves (CSSASW) system which uses a controlled vibration source that generates 'random' pulses. The 'raw' Rayleigh wave phase velocity dispersion data are used to compute shear wave velocity distribution in depth to produce a layered soil profile. Other soil properties may be obtained from the shear wave velocity profile based on available correlations. Recently, the CSSASW system was used for soil profiling in the World Port of Los Angeles. At a large fill area in the port CSSASW results clearly identify the distinct soil layers and show good agreement with available soil data from SPT and CPT borings.
