地下结构震害类型及机理研究

地下结构由于受到周围岩体或土体的约束 ,一直被认为具有良好的抗震性能。但是 ,随着地下结构数量的增多和地下结构震害的频繁出现 ,地下结构的震害问题日益受到世界各国地震工作者的高度重视 ,笔者通过对大量地下结构震害的分析研究 ,对地下结构震害进行了分类 ,并研究了震害的影响因素及机理 ,以期为地下结构的抗震设计提供科学依据和有益的参考。

Study on the Categorization and Mechanism of Seismic Damage of Underground Structures

Underground structures, being confined by the surrounding rock or soil, have long been assumed to have good anti-seismic ability. However, as the number of underground structures and frequency of seismic damage increase, earthquake professionals all over the world are more and more concerned about this problem. After investigating the seismic damage of many underground structures, the author suggests a method for categorizing these underground damage, and the influential factors and mechanism of seismic damage are studied. All these would provide scientific criteria and beneficial references to the anti-seismic design of the underground structures.
