... of the solid surface roughness. The analyses also revealed that the normalized undrained peak and residual shear strengths of the soils and interfaces are insensitive to the change in soil plasticity. The ratios between these undrained strengths and the corresponding drained strengths decrease with decreasing...

... this issue by experimentally characterizing the bond strength according to the “concrete” material strength and the interface surface roughness. Experimentation was conducted in a laboratory environment using mortar interface replicas to simulate concrete dams and medium-strength bedrock foundations. Two...

... cohesive strength to otherwise cohesionless sand. The effect of reinforcement on the friction angle was found to be insignificant. The magnitude of imparted apparent cohesion is found to depend not only on the tensile strength of the geosynthetic material but also the surface roughness changes during...

... in the laboratory pull-out test box. A series of laboratory pull-out tests was performed with a cement grouted nail in a Completely Decomposed Granite (CDG) soil. It is aimed at studying the influence of overburden pressure, soil degree of saturation, and surface roughness of soil nail on the interface shear...

Of these adjustment factors, the surface roughness is considered to be of utmost importance in that it has...

.... The test results show that the grain shape and the surface roughness, quantified with respect to the grain size, are the primary parameters controlling the interfacial shear strength at a given normal stress level. Three zones of normalized roughness associated with different shear strength levels were...
