摘要
以陕西省某高速公路的一座分离式隧道为例,分析了隧道进口表层破碎岩体在进口开挖过程中产生浅层潜在滑动的机理,并应用抗滑桩加挡土板综合支护对其进行了治理,通过工后坡体变形检测及实际施工进度证明了治理工程的有效性。
Taking a separate tunnel of a highway in Shaanxi as an example,this paper analyzed the line layer potential sliding mechanism of tunnel entrance surface broken rock in import excavation process,and made treatment application of anti-slide pile and retaining plate comprehensive support,through the work behind slope deformation detection and practical construction schedule proved the validity of control project.
