The shallow site investigation was done in the second campus of Federal University of Petroleum Resources Effurun (FUPRE) stadium and its environs with the aim to determine the shallow site level and also to estimate some geotechnical parameters for potential construction sites within the study area with the application of seismic refraction method. The research was done using seismograph (PASI GEA 24 model) using 24 geophones with 4 m spacing and the traverse distance for the area of investigation is 100m. The data acquired was interpreted after the unwanted signal has been removed in order to identify and estimate the thickness layer and velocities of different subsurface interfaces. From the three traverses employed around the investigated area, the results showed that the subsurface of the study area is made up of three layers. The first layer is a top soil with an average thickness of 7m and the P-wave velocity is 284.5 m/s. The second layer, which is a weathered Phyllite composition, has an average thickness and P-wave velocity of 24.5 m and 419.2 m/s respectively and this indicates that the saturated zone in this layer is vertically extensive. The third layer has the pwave velocity of 765.6 m/s, however, all the three layers has the same Poisson's ratio value of 0.35 and density value of 1800 kg/m3. From the values of other geotechnical parameters; which are young modulus, bulk modulus, shear modulus and s-wave velocity. It is concluded that the first two layers are poor bearing capacity that have low shear strength and high compressibility due to the low values of the parameters compared to the third layer; however an additional geophysical method is recommended for more revelation of geophysical characteristics or features.
