摘　　要：地下结构的振动特性与地面结构有很大不同,针对于地下结构特点的抗震分析方法日益受到重视,近年来取得了很大的进展。简要总结了原型观测方法的特点及研究现状;详细介绍了理论分析方法的基本原理及主要的实用抗震分析方法;对近些年来地下结构振动模型实验方面取得的成果进行了综述;对地下结构抗震研究方法的未来发展趋势进行了探讨。There is great difference in the vibration characteristics between the underground structures and the ground - surface buildings. More and more attention is paid to the seismic analysis methods aiming for the undergound structures, and there has been great progress in this field in recent years. The prototype observation methods of the underground structures are briefly summarized, the basic principle of theoretical analysis methods and the main practical seismic analysis methods are introduced in detail, and the achievements of vibration model test in recent years are summarized. Lastly, the future development trend of seismic analysis method for the underground structures is discussed.
