Tunnel anti-skid reinforcing structure suitable for underneath pass landslide
The invention discloses a tunnel anti-skid reinforcing structure suitable for an underneath pass landslide. The tunnel anti-skid reinforcing structure comprises a primary support, a secondary lining and a plurality of anti-skid piles, wherein the primary support and the secondary lining are arranged in a tunnel structure, and the anti-skid piles are arranged on the same side of the tunnel structure; and the secondary lining is fixed to the inner wall of the primary support, the anti-skid piles are evenly arranged in the shape changing direction of the tunnel structure, and each anti-skid pile is fixedly connected with a steel frame layer of the primary support through a corresponding pre-stressed anchor cable. The primary support of the tunnel structure is fixedly and effectively connected with the existing anti-skid piles on the side through the pre-stressed anchor cables, the shape and position of the tunnel structure are adjusted by applying prestress, the tunnel structure is adjusted and reinforced, the steel frame layer of the primary support is adjusted in place, the overall rigidity of the tunnel structure is improved, and the anti-skid capacity of the tunnel structure is effectively improved.
本发明公开了一种适用于下穿滑坡的隧道抗滑加固结构，包括有设置于隧道结构内的初期支护和二次衬砌、以及设置于隧道结构同一侧的多个抗滑桩，二次衬砌固定于初期支护的内壁上，多个抗滑桩沿隧道结构的走形方向均匀布置，每个抗滑桩通过对应的预应力锚索与初期支护的钢架层固定连接。本发明隧道结构的初期支护通过预应力锚索与侧方既有的抗滑桩建立固定有效连接，通过施加预应力来调整隧道结构的形状和位置，起到对隧道结构进行调整和加固的作用，使初期支护的钢架层调整到位，有利于增大隧道结构的整体刚度，有效提升了隧道结构的抗滑能力。
