Soil Liquefaction Potential of a Highway Bridge Foundation

Dynamic properties of a highway bridge foundation were determined through extensive field and laboratory tests. The liquefaction potential of alluvia materials consisting of sand material with 10 m depth was evaluated by using field data obtained from standard penetration and cone penetration tests, as well as seismic tests by measuring longitudinal and shear waves velocities. In addition the laboratory testing program has included classification tests, cyclic triaxial and cyclic simple shear test. The analyses have showed that comparable factors of safety may be obtained from both field and laboratory tests
