Abstract

Seismic refraction has long been adapted for various types site characterization studies. The method has evolved from the classical theory based on Huygens's principle involving straight propagation paths representing spherical wave front heading direction into many novel considerations involving curved-ray-path and cell based finite element techniques for tracing the propagation of seismic waves in the subsurface media and deriving the velocity of the body waves as closely approximated to reality as possible, within the theoretical and computational limits of the routines. In view of multifarious options available in the market for plotting and visualizing and interpretation of seismic sections it becomes important to understand the influence of manual and automated processing techniques on reasonability, accuracy and reliability of velocity sections derived from such techniques. This paper comparatively evaluates the merit and limitation of each of the techniques w.r.t to the site conditions, the depth of investigation and resolution. This study emphasizes the need of optimal selection of field survey and processing parameters with due regard to the constraints experienced during acquisition and processing
