灰岩地区公路隧道穿越大型溶槽坍方地段施工技术

Treatment Technology of the Soil Landslide Treatment Section of Highway Tunnel Passing through Large-scale Solution Groove in Limestone Area

公路隧道穿越灰岩地区岩溶发育不良地质地段时,隧道极易与大型溶槽相遇,阐述牛角山隧道施工中大型溶槽坍方地段处理的施工技术,以供广大同行借鉴、参考。

When highway tunnel passes through poor geologic section in limestone area where karst develops, it will easily intersect with large corrosion zone. In this paper, the treatment experience of large corrosion and landslide area is presented in the construction of Niu -jiao Mountain tunnel, for the purpose of providing reference for similar situations.
