| Abstract: | Damage to structures may be caused by large ground deformation due to seismic liquefaction. However, the research concerned is limited. The relative test equipments, test methods and specimen preparing methods of large ground deformation are discussed in this paper. The technique and results of the experiments are studied. Finally the importance of formulating constitutive models and practical prediction methods based on laboratory tests is pointed out. |
