Abstract

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.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a tunnel anti-sliding reinforcement structure suitable for passing down landslides. Background technique [0002] my country is a country with frequent geological disasters, of which landslide disasters account for about 65%. With the rapid development of my country's economy, the investment in railway and highway construction in areas with complex terrain and geological conditions in the west is also increasing. However, its construction is limited by factors such as natural geographical environment and cost, and the line has to shuttle through the mountains and mountains, which is inevitably affected by various adverse geological disasters. At present, a large number of tunnels in China are damaged by landslide deformation, causing huge economic losses and even casualties. Therefore, the treatment of landslide disasters within the scope of tunnel engineering is extr...
