Abstract

This study integrates seismic refraction technique (SRT) and laboratory test technique (LTT) methods in order to evaluates the slope stability characteristics of the sedimentary rocks at Mary-Slessor Secondary School, South-South, Nigeria. The integrated approach was adopted to investigate the material strength, soil resistivity and delineate optimal slopes with regards to the factor of safety (FOS). Three layers were delineated in the field analysis, the velocity and resistivity of the first, second and third layers range from (460.5 – 1050) m/s and (850 – 1220) Ωm at 5.61 m depth, (1705 – 2100) m/s, (560 – 650) Ωm at 7.20 m, and (2000 – 2500) m/s, (330 – 450) Ωm at 13.3 m respectively. The elastic parameters obtained from SRT and LTT ranged from (1.1 – 2021.1) kN/m2 and (1.2 – 2270) kN/m2. The result revealed the material’s strengths of the third layer formation with a high velocity and low resistivity being optimally stable with regards to FOS.
