| Abstract | The geological mapping, rock mass survey and seismic refraction survey and laboratory testing were carried out to determine the slope stability on both sections of the cut slopes a long the New Friendship Highway (km . 0+000- km. 1+600). Laboratory works were also done to generate the additional information. The potential failure slopes were divided into seven sections based on the slope geometry and properties. Within each section the possible modes of instability were identified by the kinematic method with respect to the orientation of the bedding and joint sets. The block sliding and block toppling were the most possible modes of failure. The shear strengths were obtained from the laboratory direct shear tests on lapped surface samples, from the geomechanics classification, and from the Barton's equation . The Barton's s h ear strength was close to t he field shear strength that was used to determine the factor of safety o f block slides. The limiting equilibrium analysis was used to calculated the factor of safety of possible sliding blocks and the limited dimension of blocks in toppling cases. The results showed that Sloped No. III and IV can develop both block sliding and block topping. |
