Figure below shows the results of seismic refraction test at a site with the top soft soil layer underlain by the bedrock. In order to decide the suitability of this site for deep foundation, depth to the bedrock must be determined. From the results of the seismic refraction test, calculate the depth to the bedrock, zc, and select the correct answer from the choices provided: Seismic Refraction.jpg
