本文介绍了目前工程抗震与土动力学研究中的重点课题“液化地面大位移及其对工程的影响”最近十余年来（1983—1994）的主要研究成果及其涉及的主要内容：中、日、美等国家因地面大位移引起的震害情况；土液化后的特性；地面位移量的预测；工程结构抗地面水平大位移的措施，特别是地下生命线工程的抗水平位移的设计对策。
This paper introduces the key research topics in the current research on earthquake resistance and soil dynamics: “Large displacement of liquefied ground and its impact on engineering”. The main research results in the recent more than ten years (1983-1994) and the main contents involved: Japan, the United States and other countries due to ground displacement caused by the earthquake damage; the characteristics of the soil after liquefaction; ground displacement prediction; engineering structures against ground level large displacement measures, especially the design of underground lifeline engineering horizontal displacement resistance.
