摘　　要：浅埋暗挖法是地下暗挖工程中常用的施工工法,常用于隧道、市政管沟工程。因其工法特点,施工过程中遇见文物建筑或其他重点构筑物,需根据现场情况采取相应施工措施进行精细化控制,将施工影响放置在可控范围内。断虹桥作为故宫博物院内最古老的建筑,历经元明清三代六百年风雨屹立不倒,具有建设年代久远,文物级别高、建筑结构资料缺失,施工难度极大等诸多特点。本文以故宫博物院基础设施工程中下穿断虹桥暗挖施工为例,梳理浅埋暗挖施工中穿越文物建筑及重点构筑物的解决思路、总结施工及保护措施,整理解决思路,为相关工程提供参考。Shallow buried-tunneling method is a common practice for underground construction.It is often used for building tunnels and urban pipeline and drainage system.Due to the special process involved,during shallow underground tunneling,precise control is required based on onsite conditions when a cultural relics buildings or other significant structure is encountered to ensure that the impact of the construction work is controllable.The Broken Rainbow Bridge is the oldest building in the Palace Museum,witnessing the ups and downs over three dynasties,namely,Yuan,Ming and Qing,in China's history,and still standing after 600 years since its completion.Due to its long history,it is considered a significant cultural relics buildings which was extremely difficult to build.However,information relating to its original constructionwork and structure isvery scarce.Taking underground tunneling under the Broken Rainbow Bridge during the infrastructure development in the Palace Museum as an example,this paper reviews the ideas about shallow underground tunneling under cultural relics buildings and significant structures,summarizes construction and conservation measures,and identifies relevant solutions before proposing feasible approaches to similar construction work in the future.
