摘要
基于对汶川地震中遭受破坏的山区岩体中特种结构的现场震害调查,研究了岩体中结构的震害宏观现象和机理;建立基于波动理论的有限元数值模拟方法,分析了山区岩体中结构的地震响应及其受岩层结构面和断层带的影响。
Based on site exploration on earthquake damage of special underground structures subjected to Wenchuan earthquake in 2008,macro-phenomena and mechanism of earthquake damage of special underground structures in mountainous region rock were investigated. Earthquake response characteristics of the underground structures and effects of construction delamination and fault of rock on earthquak-resistant characteristic of the underground structures are discussed by means of FEM numerical stimulation analysis on the basis of theory of wave motion.
