Abstract
AbstractIn this paper, an attempt is made to capture the seismic stability of a finite slope reinforced with micropiles using the original pseudo-dynamic (OPD) approach. The stability of the slope is evaluated using the limit equilibrium method considering c-ϕ soil. The study is performed by assuming a circular slip surface passing through the toe of the slope. The effect of various parameters such as horizontal (kh) and vertical (kv) seismic acceleration coefficients, slope angle (i), angle of internal friction of the soil (ϕ), amplification factor (fa) and angle of inclination of micropiles (θb) on the stability of the slope is explored in terms of the factor of safety (FOS). Under the seismic condition, the stability of a slope along with micropiles is found to be affected less compared to that of a slope without micropiles.KeywordsEarthquakesLimit equilibrium methodMicropilesPseudo-dynamic approachSlope stability
