Abstract

A

Dynamic elastic moduli like , μ, and μ of the foundation rock of a dam have been determined by finding ‐ and ‐velocities by seismic refraction with a hammer as source. Some parameters such as “fracture frequency” and “rock quality designation” (RQD) of the foundation rock have been derived using “average regression curves” and ‐velocities. By comparing /μ with , a few locations showing weathered conditions have been demarcated. This compares well with RQD values of those locations.
