新奥法技术和复合式衬砌为大跨度黄土隧道的设计与施工提供了条件。国内外学者对大跨度隧道进行了许多研究,取得了一些成果;我国在大跨度黄土隧道的施工技术上取得了一些重大突破。文章总结了大跨度黄土隧道的施工方法、开挖效应、施工监测和隧道裂损原因及处置等方面的研究和技术现状,对大跨度黄土隧道的设计与施工提供一定的工程参考。 The new Austrian technology and composite lining technology for the design and construction of large-span loess tunnel provided the conditions. Many scholars at home and abroad have carried out many studies on long-span tunnels and achieved some results. Some major breakthroughs have been made in the construction technology of long-span loess tunnels in our country. This paper summarizes the research and technical status quo of construction methods, excavation effects, construction monitoring, cause and disposal of long-span loess tunnel, and provides some engineering references for the design and construction of long-span loess tunnel.
