复杂条件下山岭隧道施工不良地质及处治技术

白涛隧道项目所处地区存在着大量的不良地质,主要包括灰岩区岩溶与突水(泥)、软弱围岩大变形与塌方,隧道穿越段地质条件复杂,施工难度大、工期长,为了减少隧道施工过程中发生岩溶突水、塌方等事故灾害,并且为隧道施工过程中不良地质处治提供技术指导确保施工安全。

There are a lot of bad geological conditionswith thetunnel projectin the area of Baitao,including karst and water inrush(mud)in limestone area,large deformation and collapse of soft surrounding rock,complex geological conditions of tunnel crossing section,high difficulty in construction and long construction period.In order to reduce the karst water inrush,collapse and other accidents in the tunnel construction process,this paper provides technical guidance for the poor geological treatment during the tunnel construction to ensure the safety of construction.
