Abstract

In conventional way, investigation of the subsurface parameter is determined from boreholes data. However, the information retrieved from a bore log only provides information at a discrete location. Geophysical method such as seismic refraction has been routinely used to compliment the ‘missing’ boreholes information as it offers continuous information along the survey line. This paper presents the relationship between seismic refraction method and borehole logging in a granitic area at Ulu Tiram, Johor. Three lines of seismic survey were carried out to assess the subsurface for quarry development. Two boreholes were drilled along the seismic line in the effort to find relationship between information gathered from those methods. The seismic survey results are evaluated along with SPT and RQD information. Results for the correlation of seismic refraction survey and borehole data can be used for better subsurface characteristics exploration between boreholes besides providing data rapidly at a relatively low cost and give benefits in terms of work time.
