高速公路隧道施工工艺控制
浅析高速公路隧道施工工艺控制
摘要：山区高速公路选线不可避免地会出现线路斜穿地形等高线，隧道与山体呈斜交进洞，洞口段不可避免地存在浅埋和偏压问题，洞门位置的选定对边坡稳定和施工难度的影响极大。本工程隧道进口属于斜交偏压隧道进洞实例，为了保证进洞安全，尽量少破坏原有植被，对原设计刷坡进洞方案进行优化，采用了相对应的方案进行施工作业。

abstract: the mountainous area highway route will inevitably appears inclined to wear contour line terrain, tunnel and mountain was a into the hole, the mouth of the cave section is unavoidable in the shallow and bias problem, dongmen
position of the selected slope stability and the influence of the difficulty in construction is great. this engineering tunnel under import oblique bias tunnel into the hole examples, in order to ensure safety into the hole, as far as possible destroy the original vegetation, the design scheme of slope into the hole brush optimization, the corresponding solutions for construction work.
