目前地下工程抗震设计一般是基于传统的拟静力计算.这与实际地震响应相差较远。1995年日本阪神大地震对地下结构的破坏,打破了土木工程界忽视地下工程抗震的固有观念。掀起了一股地下工程抗震研究热潮。论文对地下工程地震响应分析的解析法、半解析法与数值计算方法的发展现状与存在问题进行了较为全面的阐述。结合地下工程抗震设计的实际需求,探讨了地下结构地震响应理论分析的发展趋势。
Underground aseismic design is mainly based on traditional pseudo static calculation, which is very different from actual seismic response. Hanshin-Awaji earthquake in 1995 seriously damaged underground structures, which changed the traditional view of civil engineering circle ignoring a- seismic structure of underground project and stimulated research on underground aseismic structure. The authors fully review the current status and prob- lems of the analysis method, semi-analysis method and numerical computation method and discuss the development trend of seismic response theoretical analysis on underground structures.
