Abstract:

Liquefaction phenomenon which has produced severe damage all over the world was studied under earthquake record of 0.5g; one of the major effects of liquefaction is lateral spreading. Lateral spreading occurs in sloping grounds and can cause serious damage to structures and lifelines. The objective of this paper is to study the effect of earthquake shaking on soils and slope stability using Geo Studio software 2007. The applicability of the analysis is demonstrated by analysis various slope and embankments subjected to earthquake shaking. This study investigated the effect of embankment slope angle and its geometry on liquefaction. Pore water pressure can be increased by 100% to 35% as β ranged from 35ͦ to 45ͦ respectively, it can see that liquefaction zone induced by earthquake can eliminate as flattering slope and mean while reduced lateral speared displacement. Three case studies are providing to evaluation cyclic stress ratio (CSR) due to earthquake and lateral speared for soils.
