摘　　要：砂士地震液化引起的地面大位移会对结构产生灾难性的破坏，这已引起了人们的重视，但对其进行研究时间较短。作者在大量阅读有关资料的基础上，详细介绍了液化后地面大位移研究的室内试验设备、试验方法、试样的制备、试验的主要规律及国内的研究现状，并对试验技术和结果进行了探讨，指出以室内试验为基础提出液化后的本构模型及实用计算方法是今后工作的重点。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.
