地下变电站结构抗震分析及设计方法研究

Seismic Analysis and Design Method of Underground Substation Structure

结合我国上海、北京地区地下变电站的结构特点,综合已有的地铁车站、地铁隧道等抗震设计研究成果,对地下变电站结构的抗震分析与设计进行系统地分析与探讨。地下变电站的抗震设计在一定程度上能参考已有的地铁车站的抗震设计方法,但还必须考虑其自身楼板开孔等特点进行抗震设计,同时要对其抗震构造措施进行专门的研究。

Based on the existing seismic design method of subway station and tunnel structures, seismic re-sponse and design concept of underground substations were discussed. The characteristics of underground sub-stations in Shanghai and Beijing were particularly interested. To some extent, the seismic design work of un-derground substation can refer to that of subway station and tunnel structures. However, due to its own struc-tural characteristics, such as floor holes, the design of underground substations requires special considera-tions. Moreover, the seismic structural detailing measures should be specially studied.
