谈地下结构的震害特点

On seismic features of underground structures

基于地下结构的概念,介绍了地下结构的类型及形式,针对地下结构的特点,分析了地下结构的震害特性与地震反应时的特征,指出地下结构震害发生会波及其周边结构,且修复比地面结构难度大,因此研究地下结构的抗震性能很有必要。

Based on the concept of the underground structure,the paper introduces the types and forms of the underground structure,analyzes the seismic features of the structure and the characteristics of the seismic response according to the features of the underground structures,and points out the seismic disasters of the structure can affect its surrounding structures with more difficulties than the ground structure in its repair,so the research on the seismic performance of the structure is necessary.
