Abstract

In this paper, the design of nailed soil slopes based on the pseudo-static and pseudo-dynamic analyses have been investigated and compared. In pseudo-static analysis a simple rigid body analytical model is used to evaluate the forces in the nails required to maintain the slope in stable condition during an earthquake. Pseudo-dynamic analysis incorporates a finite shear wave velocity based on the assumption that the shear modulus is constant and only the phase and not the magnitude of the acceleration is varying with depth. The effects of inclination of the nails and the coefficient of horizontal acceleration on the required reinforcement length ratio have been presented.
