摘　　要：浅埋暗挖技术是以加固和处理软弱地层为前提,通过选用合理的开挖方式,来保证施工安全和控制地面沉降。同时具有灵活多变、造价低、隧道结构强度高等优点。本文结合具体工程实例,重点分析了暗挖技术在地下不良地段的应用。Shallow-buried underground excavation technology has precondition of reinforcing and processing weak formation. Reasonable excavation method is selected to ensure construction safety and control land subsidence. Meanwhile, the technology has the advantages of high flexibility, low cost, high tunnel structure strength, etc. In the paper, concrete engineering examples are combined for mainly analyzing the application of underground excavation technology in bad underground section.
