Abstract: | The required reinforcement force to prevent instability and the yield acceleration of reinforced slopes are computed under
seismic loading by applying the kinematic approach of limit analysis in conjunction with the pseudo-dynamic method for a wide
range of soil cohesion, friction angle, dilation angle and horizontal and vertical seismic coefficients. Each parameter threatening
the stability of the slope enhances the magnitude of the required reinforcement force and vice versa. Moreover, the yield
acceleration increases with the increase in soil shear strength parameters but decreases with the increase in the slope angle.
The comparison of the present work with some of the available solutions in the literatures shows a reasonable agreement. |
