摘要
在日本阪神地震中遭受地震破坏的地铁地下结构中，仅大开车站中标准段一处区域发生了完全塌毁，其它地铁车站、隧道的震害程度均相对其要轻微。利用能够合理模拟地下框架结构损伤破坏的数值分析模型，对大开车站标准段、中央大厅段以及区间隧道结构的地震破坏反应进行了数值模拟分析，探讨了造成上述现象的原因。结果表明：不同断面宽度以及埋深导致大开车站标准段、中央大厅段以及区间隧道结构所受的上覆土压不同，使三者立柱在地震作用中处于不同的轴压比状态下工作，并使得三者不同刚度的结构框架在地震作用中出现不同程度的损伤与刚度退化，继而导致三者立柱出现了不同程度的水平相对变形。最终大开站标准段立柱由于较高的轴压比下受到过量的水平相对变形而发生破坏，从而导致整体框架结构的严重破坏；其余二者则由于立柱处于较低的轴压比下，所受水平相对变形处于立柱变形能力范围内，而未发生立柱破坏，进而使得整体框架保持了承载能力。
Abstract
During the Kobe earthquake in Japan
different degrees of earthquake damage occurred on the subway underground structures. Only one zone of the standard section of Daikai station totally collapsed
while the other zones of Daikai station
its running tunnels and other subway underground structures did not have serious earthquake damage. In this paper
the earthquake damage responses of the standard section
central hall and running tunnel structure of Daikai station were analyzed based on nonlinear finite element analyses which can reasonably simulate the damage of underground structures. Numerical results indicate that different width of structural cross section and burial depth lead to different overlying earth pressure on the structures at the standard section
central hall section and running tunnel section. The different overlying earth pressure generated different axial compression ratio of the three structural columns. In addition
the three structures with different lateral racking stiffness had different degree of damage and stiffness degradation
and further led to different lateral racking deformation. Eventually
the columns of Daikai station standard section destroyed due to the excessive relative deformation under the high axial compression ratio
which caused the total collapse damage to the entire frame structure. On the contrary
the columns of central hall and running tunnel section have not destroyed because there were not excessive relative deformation under the lower axial compression ratio
which kept the bearing capacity of the entire frame structure.
