摘　　要：在公路路线走廊困难地段、高位崩塌落石发育路段、高陡边坡或老虎嘴路段、环境敏感路段等地方设置防灾减灾明洞或棚洞,被认为是应对边斜坡不良地质病害、保障边坡安全、保护自然环境的有效方法,近年来在山区公路建设中得到了大量应用。详细分析了明洞与棚洞的定义与分类标准,介绍了明洞与棚洞在公路与铁路行业的发展历程与国内外应用现状,最后从综合立体防护、高防护性能、快速应急响应、应用环境多样性等方面对明洞与棚洞的发展趋势进行了展望,供同行借鉴参考。It is considered as an effective method to deal with adverse geological defects of side slopes,ensure slope safety and protect the natural environment to set open holes or shed holes in difficult sections of highway route corridors,high-level collapse and rockfall development sections,high and steep slopes or other dangerous sections(tiger mouth shaped section),environmentally sensitive sections and other places.In recent years,it has been widely used in highway construction in mountainous areas.In this paper,the definition and classification standard of open cut tunnel and shed tunnel are analyzed in detail,the development history and application status of open cut tunnel and shed tunnel in highway and railway industry at home and abroad are introduced,and finally the development trend of open cut tunnel and shed tunnel are expected from four aspects:comprehensive three-dimensional protection,high protection performance,rapid emergency response,and diversity of application environment,for the reference of peers.
