【摘要】 城市轨道交通地下结构需要进行抗震设计,但我国缺乏成熟的地下结构抗震设计流程。依托GB 50909—2014《城市轨道交通结构抗震设计规范》,对城市轨道交通地下结构抗震设计中的关键问题及流程图进行了研究,提出了一套抗震设计流程,并对一个典型的城市轨道交通区间隧道抗震设计进行了讨论。更多还原

【Abstract】 Seismic design is critical for the underground structures of urban mass transit,but a mature seismic design process is missing in C hina. B ased on the " C ode for S eismic D esign of U rban Rail T ransit S tructures "( G B 50909-2014),key problems in seismic design of urban rail transit underground structures and the design flowgraph are studied,a newdesign process is proposed besed on the study of a typical seismic design for the traffic interval tunnel of urban rail transit.更多还原
