dc.description.abstract | A city of high population growth and rapid development founded on top of soft, lacustrine and alluvial deposit, Hawassa is located in a seismically active area of the country. On top of this, the fact that it is a lakeside city makes liquefaction a potential hazard that calls for serious consideration. This thesis evaluates the potential of liquefaction of Hawassa city based on data acquired after selecting sites in and around the city. Based on these data, the level of hazard with respect to magnitudes of earthquakes and vulnerable layers thickness with depth is assessed. SPT and shear-wave velocity based simplified procedure methods are used to evaluate the liquefaction potential of the study area. This study evaluates liquefaction resistance of the soil against earthquake induced loads expressed in terms cyclic shear stress of the study area. The results of the analyses are compared with factor of safeties recommended by ES-EN1998:2015 and BSSC 2000. Majority of the results indicated liquefaction hazard is minimal within the city with some parts showing marginal signs of liquefaction, leading to the recommendation of site specific studies for important structures. | en_US |
