【摘要】 随着我国交通基础设施的飞速发展,大量的铁路、公路隧道以及城市地铁相继修建。然而,国内外现有抗震规范中关于地下洞室等地下结构的条文都十分简略,难以适应高烈度地震区地下洞室的建设发展。在对以往隧道震害调查的基础上,分析隧道震害破坏的主要形式,并总结影响隧道震害的主要因素,对当前隧道抗减震设计具有一定的指导意义。更多还原

【Abstract】 With the rapid development of Chinese transportation infrastructure,many railways,highways and city subway tunnels have been built.However,existing seismic norms about underground tunnels and other underground structures of the provisions are too briefly at home and abroad,which cannot adapt to the development of underground caverns at the high intensity earthquake zone construction.Based on the research of tunnel earthquake damage,this paper analyzes the main forms of tunnel damage,and summarizes the reasons of tunnel damage,which have important instructing role for tunnel aseismic design.更多还原
